Decimal not supported as primitive
TargetParameterCountException while deserialization
in my app the BinarySerializer is used for Serialization of Tcp/Ip communication, one TargetParameterCountException is thrown while calling Deserialize method. i have prepared a simple Project for test it, there is 3 constructors in Header.cs, if the both constructors with Parameters are commented out, no exceptions occur, otherwise, one TargetParameterCountException is from code line
value = subType.Constructor.Invoke(parameterValues) in class ObjectValueNode thrown.
i can't attach source code per zip, so i wrote it in one txt file, which has 7 simple .cs files, please have Patience!
Thanks
the constructor is called multiple times during deserialization
Hi Jeff,
during serialization, the constructor is called multiple times.
My class class contains a list and a count-property without a setter. In this case, the serializer use the special constructor, which contains the appropriate parameters. My Constructor throws an argument exception, if the count does not match to the given list.
The final constructor call is Ok. But the previous calls does not contains the fully list from stream. Because of the difference between the count and list, the constructor throws an argument exception. Can you turn off the unnecessary constructor calls before the final call?
Regards
Dirk

Should I use value converter or a custom serialization?
Hello, first of all I am sorry if this isn't the correct place to ask, I am not so familiar with github.
This framework is amazing, I'm glad that I found it, but I am a bit confused about Value Converter.
I have a packet structure where one of its props is the payload length (as UInt16), it comes "ciphered" (xor with 0x1357) and I am not sure if this is the proper use for a Value Converter.
This is most because I don't get why I can't set a ConverterType for FieldOrder, maybe because the length result from the convert may be different of the field size?
I know I can set a the converter as a proper of FieldSize but then I am defining the size two times because I already have set the variable as UInt16.
Anyway, really sorry if this is not the correct place or my question offends you (I don't know if my question is stupid), I readed the readme many times but I don't get it.
Thank!
EDIT: nvm, I misunderstood all, value converter is for bindings (#19). Seems like the proper way to do this is having some method that "cipher" all the header before serializing the packet, and decipher after deserializing it.
Looks like I did not read well all readme (excuse me, english is not my native language).
EDIT2: I think this will be a good moment to use a custom serialization, What do you think? The code will be cleaner and will abstract all the packet processing (encryption, compression and checksum), is there something I am missing or its so good as it sounds?
BinarySerializer with Windows Phone 8.1
I am getting a compatibility error message when I try to install the BinarySerializer package in a WindowsPhone 8.1 project. Should a PCL (portable) class library not work also for WinPhone 8.1 ?
feature request: how about extending this to read and write EXI
Just a feature request, but it would be cool to get your thoughts.
-thanks

Getting Started, Need some enlightenment.
Sorry, Posted to wrong repository.
SerializeWhen Attributes And'd as opposed to OR'd?
Assume the following:
OrderAdditionalKegs only needs to be Serialized when PartyBusIsComing == true AND
ModelsAtPlayHouseMansion >= 20
[FieldOrder(0)]
public int ModelsAtPlayHouseMansionCount {get; set;}
[FieldOrder(1)]
public bool PartyBusIsComing {get; set;}
[FieldOrder(2)]
[SerializeWhen("ModelsAtPlayHouseMansionCount", true, ConverterParameter = "20", ConverterType = typeof(GreaterOrEqualConverter))]
[SerializeWhen("PartyBusIsComing", true)]
public bool OrderAdditionalKegs {get; set;}This will not work because SerializeWhen are always ||'d together.
Can you show an example where a converter accepts more than one argument?
BinarySerializer deserialization performance
I did some measurements regarding the performance of the BinarySerializer serialization/deserialization, and I got quite huge times for the deserialization.
A binary message with some about 10000 bytes needs each time about 1200 msec for deserialization (the BinarySerializer object is created only once and reused, no debugger events were defined during this measurement).
What is weird is that the serialization process that generates the 10000 bytes back from the c# class takes only 10 msec or even less.
Only the deserialization of each length-prefixed string takes 15 msec (to get these times I had to reactivate the debug events)

The c# class looks like this:
public class Entry
{
[FieldOrder(0)]
public byte Length { get; set; }
[FieldOrder(1)]
[FieldLength("Length")]
public string Value { get; set; }
}
public class ElementClass
{
[FieldOrder(0)]
public Int32 B_ID { get; set; }
[FieldOrder(1)]
[FieldLength(51)]
public Entry B_Name { get; set; }
...
}
Earlier I had this code to get the length-prefixed string by reading "manually" the length from the first byte:
...
private string _B_Name;
[FieldOrder(1)]
[FieldLength(51)]
[SerializeAs(Encoding = "UTF-8")]
public string B_Name //{ get; set; }
{
get
{
return this._B_Name;
}
set
{
this._B_Name = LengthPrefixedStringToString(value);
}
}
...
where:
internal static string LengthPrefixedStringToString(string value)
{
string tempStr = String.Empty;
if (value != null)
{
try
{
value.Trim();
int strLen = value.Length;
if (strLen > 0)
{
if (strLen > 255) {
throw new Exception("Maximum length allowed for pascal strings is 255");
}
char lenCh = value[0];
byte len = Convert.ToByte(lenCh);
if (strLen > (int)len)
{
tempStr = value.Substring(1, len);
}
}
}
catch { }
}
return tempStr;
}
With this code, the deserialization of the 10000 bytes from the binary message takes only 30 msec or even less (still not perfect, if I compare to the serialization time in the other direction, but much much better than the 1200 msec above).
Is there any way to significantly improve the performance of the deserializer, especially regarding such length-prefixed strings, constructed as above ?
Deserialization requires all setter-properties to be public, making immutable classes impossible
I just started using this library as it seemed to fit my needs to control the output to a high degree. (I was previously using the Marshal-class).
However, all the objects that I want to serialize and deserialize are immutable, with all the properties set through the constructor. Is there any way to keep them immutable by decorating the parameters of the constructors, or some other way?
Add support for default subtype
It would be nice if you could specify a default subtype for unknown subtype values.
Support concept of visited fields and forward bindings for multibinding
Start tracking whether fields have been visited or not and use this info for both diagnostics and forward multibindings. As an example,
public class FieldLengthMultibindingClass
{
[FieldOrder(0)]
public int Length { get; set; }
[FieldOrder(1)]
[FieldLength("Length")]
[FieldLength("Length2")]
public FieldLengthMultibindingInternalClass Internal { get; set; }
[FieldOrder(2)]
public int Length2 { get; set; }
}Although this doesn't currently work during derserialization, there really is no reason it couldn't, with the following logic:
- Length field is successfully deserialized
- Internal field attempts to resolve bindings and realizes that while Length field is valid, Length2 field has not been visited yet and cannot be resolved. However, since all binding values must agree, Internal proceeds to deserialize based on value of Length field. Internal also registers this as a "check" value with Length2 field.
- Length2 field deserializes and checks value against check field.
The same check concept would allow for CRC checks, if that's something we want...
Multiple bindings to a single source must have equivalent target values?
I'm baffled.
I'll update test case shortly.

IgnoreAttribute being .. ignored?
Hi, me again.
I am having issues with the IgnoreAttribute in certain cases. I have used it elsewhere, and it works
However, in one of my classes, I get at exception when deserializing.
System.InvalidOperationException: 'Module' does not have a FieldOrder attribute. All serializable fields or properties in a class with more than one member must specify a FieldOrder attribute.
If I comment out these fields, the deserialization works perfectly. Nothing in the object being deserialized is called "Module", so I assume that's something in the serializer?

Add forward binding check
Depending on the type of binding and mode it may make sense to add a forward binding check. We need a better way of describing the nature of bindings and whether or not forward bindings are allowed. For example, endianness is valid for forward bindings but length is not. Need to think about this...
Access FieldLength attribute value from IBinarySerializable class?
To interface with some legacy hardware a couple custom (de)serializers are needed for special data types that have variable but predefined lengths (i.e. length not defined in the data but by protocol specs). I have a working IBinarySerializable class but need to know how many bytes there are to generate or parse for a specific instance of the class. It appears that LimitedStream has the information I want in MaxLength, but as it is an internal class to BinarySerializer, I can't access it.
Is there a way, in an IBinarySerializable based class, to figure out how many bytes can be read or written (without wasting time probing, causing exceptions and catching them)? Thanks!
CoreClr Update?
Any interest in getting this up and running with rc2*? Appears to take lots of jumping through hoops in the reflection namespace.
[FieldLength] for null string
It seems that the reserved field length for a string is ignored if the string is null. If the string is empty, it works fine.

Indexer support in binding paths

InvalidOperationException when deserializing byte stream into bool array
I have a class as follows:
public class InputsStateFrameData : FrameData
{
public InputsStateFrameData(bool[] inputs)
{
//Debug.Assert(inputs.Count == 16, "There should be 16 inputs.");
Inputs = inputs;
}
[FieldCount(16)]
public bool[] Inputs { get; }
}
It's a part of a full message frame, and I can serialize whole frame using BinarySerializer without problems. When I try to deserialize serialized byte stream or prepared array of bytes:
0xFF,
0x13,
0,
1,
0,
1,
0,
1,
0,
1,
0,
1,
0,
1,
0,
1,
0,
1,
0xFE
I get InvalidOperationException with inner ArgumentException:
Additional information: Cannot widen from source type to target type either because the source type is a not a primitive type or the conversion cannot be accomplished.
It is thrown by the Array.SetValue method in SetCollectionValue method from PrimitveArrayValueNode
protected override void SetCollectionValue(object item, int index)
{
var array = (Array)BoundValue;
array.SetValue(item, index);
}
When I tried replacing array by List it doesn't work anyway, just the exceptions are different:
The value "0" is not of type "System.Boolean" and cannot be used in this generic collection
This method tries to set boolean value with byte without any conversion, so it throws exceptions like that.
I am wondering why this part:
var items =
DeserializeCollection(stream, eventShuttle).ToList();
var itemCount = items.Count;
/* Create final collection */
Value = CreateCollection(itemCount);
/* Copy temp list into final collection */
for (var i = 0; i < itemCount; i++)
SetCollectionValue(items[i], i);
Is implemented that way, iterating with SetCollectionValue instead of just using CreateCollection with items enumerable, which uses TypeConverters.ConvertTo method to convert deserialized value into the collection child type.
[FieldCount] does not work on byte arrays
When trying to deserialize byte array object with FieldCount attribute , an exception occures: System.InvalidOperationException : No length specified on byte array.

Non-generic Deserialize
I'm not that familiar with git and github, so I was unsure how to create a pull request.
I found that it was needed to call a non-generic Deserialize() in my code. This could be solved by adding this to BinarySerializer.cs:
public object Deserialize(Stream stream, Type type, object context = null)
{
RootTypeNode graph = GetGraph(type);
var serializer = (ContextValueNode)graph.CreateSerializer(null);
serializer.EndiannessCallback = () => Endianness;
serializer.EncodingCallback = () => Encoding;
serializer.Context = context;
serializer.Deserialize(new StreamLimiter(stream), _eventShuttle);
return serializer.Value;
}
and change the existing methods to this:
public T Deserialize<T>(Stream stream, object context = null)
{
return (T) Deserialize(stream, typeof(T), context);
}
public T Deserialize<T>(byte[] data, object context = null)
{
return (T)Deserialize(new MemoryStream(data), typeof (T), context);
}
Null-terminated string will not fully deserialized
Serialization of following is running fine! But the deserialization is going wrong! It seems, that the deserialisation of the string property is finished after the first 0 byte. What can I do to solve this problem?

}Deserialization stops before the object is completely
In the event that the stream is too short to fully serialize the object, an object is returned. The missing properties have values that have been assigned by the constructor.
In this case I expect any exception or the result is null.
Is there a way to verify that all properties have been read from Stream?

Attempting to serialize DateTime ends in StackOverflowException
I attempted serializing the following object
[Serializable]
public class smallCase

The code being executed is simply

BinarySerializer bs = new BinarySerializer();
bs.Serialize(ms, sC); // << stack overflow here

What is licence for using binaryserializer and where can be found documentation?
OutOfMemoryException when deserializing array of int

Error during deserialization from a NetworkStream, with SubType and IBinarySerializable
I'm attempting to deserialize from a NetworkStream. In my case, I'm using the SubType attribute to target a type that contains an IBinarySerializable type.
Take a look here
Does this look right? Maybe there is a better way of going about this.

Binary protocol with ASCII characters
We have to exchange data with some external partner which uses a binary protocol with ASCII characters and I am not sure if the de-/serialization can be achieved with the help of the BinarySerializer.
For instance all value fields are separated with the ";" delimiter (ASCII code 0x3B). For example:
class SampleData1
{
string id;
string value1;
int value2;
int value3;
}
initialized for instance with
id = "ID1";
value1 = "abc";
value3 = 7;
(value 2 on purpose not initialized->default value should be used).
According to the required protocol a string can have the meaning "string value" (in this case it is delimited with the string identifier " = 0x22) or "string identifier" (transported without string identifier).
The class above would be binary serialized as (in ASCII printable representation, not hex):
ID1;"abc";;7;
To get things even more complicated, lists (arrays) are also supported. The arrays are delimited with "[" and "]" and the array elements are separated with ",". The aggregate types (classes) are additionally delimited with "{" and "}".
For example an array of 2 SampleData2 elements (the number of array elements is dynamic, and should be determined by the BinarySerializer by recognizing the "[" and "]" delimiters), where SampleData2 is defined as:
class SampleData2
{
SampleData1 data1;
int var1;
}
would be serialized to (in ASCII printable representation) as:
[{{ID1;"abc";;7;};3},{{ID2;"def";;;};44}]
(in this example var1 is 33 in the first array element and 44 in the second)
The classes and arrays can be hierachically cascaded (that means classes may contain other classes or arrays and so on).
Would be possible to implement such a protocol with BinarySerializer ? Are there any samples for similar protocol available ?

}serialization of S7-String
Hi Jeff,
I like to create an class, that contains the properties of a S7-String.
- MaxLength
- CurrentLength
- Value (String)
Serialization should return a stream of length Maxlength + 2 (bytes of max and current length).I would not use constants and bind the MaxLength property to the FieldLengthAttribute of the property Value. However, this leads to the result that the length of the stream depends on the property value and not on the property MaxLength.
Is there a way to define it without using the interface IBinarySerializable?
Best regards

It would be really helpful, if the BinarySerializer would track the actual stream position, aditionally to the name of the deserialized node. Could you please add the position in the binary stream in the OnMemberDeserializing event ?
Multiple FieldLength, FieldCount bindings not supported
This could be useful in cases where there are multiple source fields that must be in agreement and must be updated during serialization. Case in point:
public class Block
{
[FieldOrder(0)]
public int Type { get; set; }
[FieldOrder(1)]
public int Length { get; set; }
[FieldOrder(2)]
[FieldLength("Length", ConverterType = typeof(SummingValueConverter), ConverterParameter = -12)]
[FieldLength("Length2", ConverterType = typeof(SummingValueConverter), ConverterParameter = -12)]
//[Subtype("Type", )]
public BlockBody Body { get; set; }
[FieldOrder(3)]
public int Length2 { get; set; }
}Just left alignment
Hi Jeff,
As I understand FieldAlignment attribute sets both left and right alignment. I did not find how to set just left alignment, not both (I need it to describe DCE RPC message). Is it possible now?
Thank you in advance.
It would be nice if field endianness was bindable
Rather than having to write code, I want to say
[FieldEndianness("Endianness", 0x1A2B3C4D, Endianness.Big)]
Once dnx port is complete, swap out locking scheme for concurrentdictionary
Both top-level graph management and subtype management could probably benefit from concurrentdictionary
Deferred length calculation in bounded stream
Doing way too much to support the stupid ngpcap format. Now probably need deferred length calculation to support late binding of endianness...
SubtypeAttribute seems not to work

}I have defined a class that holds different objects in the property Data. See attached file MySource.txt. I use the SubtypeAttribute and have defined the different objects. That leads to exception during serialization and derserialization.
Is there something wrong in my class defintion? Please keep me informed!

Char not supported as primitive
Add ability to load endianness from a variable
I can think of a few use cases where endianness is specificed within the format.
I'd be awesome if endianness could be loaded from a variable!
Remove restriction that multiple bindings must have the same configuration
Bindings targets to multiple sources can be generalized, even for subtype attributes. The only restriction should be that bindings with the same configuration must agree between multiple sources.
Another Chunk Container Error... now on Serialize: Not a bindable source?
I'm coming across an issue again with nested subtypes. This time it occurs on serialization. What's baffling me is that It binds fine by itself, but when nested it doesn't work. It also doesn't work nested when I manually implement IBinarySerializable

Proper usage of Value Converter
I may have misunderstood how to use a value converter during serialization. I have a field that should be serialized to a UInt, but deserialized to a DateTime.
I have a class that is defined like so:
public class ValueUpdateMessage
{
[FieldOrder(0)]
public UInt TimeStamp { get; set; }
[FieldOrder(1)]
public byte NewValue { get; set; }
}
Since I am working with .Net and DateTime, I would like to change my representation of the message to
public class ValueUpdateMessage
{
[FieldOrder(0)]
public DateTime TimeStamp { get; set; }
[FieldOrder(1)]
public byte NewValue { get; set; }
}
since that makes date times easier to work with. As of now, I can achieve this by introducing an extra member:
public class ValueUpdateMessage
{
[Ignore]
public DateTime TimeStamp
{
get { return ConvertToDateTime(UnixTimeStamp); }
set { UnixTimeStamp = ConvertToUnixTime(value); }
}
[FieldOrder(0)]
public DateTime UnixTimeStamp { get; set; }
[FieldOrder(1)]
public byte NewValue { get; set; }
}
However, it would be a lot cleaner to use the class as defined in 2. I saw the example with a value converter in the Readme, but I can't get it to work. The FieldOrder attribute does not have the ConverterType field, so I tried using one of the others, such as
[FieldOffset(0, ConverterType = typeof(DateTimeToUnixTimestampConverter)], and
[FieldLength(4, ConverterType = typeof(DateTimeToUnixTimestampConverter)]
Is there a straight forward way to do this?
Chicken and Egg when working with EA-IFF 85
Having a hard time finalizing my implementation for some knarly EA-IFF 85 form chunks.
No matter how I strucuture or wire it up, I always end up having to implement IbinarySerializer. The stream position refuses to increase when I try to add padding via converts or props.
there are 0 or more REFE chunks and the AUTH chunk is optional.
here's one (of about 10) different ways I've tried implementing REFS:
'''
///
/// There is a REFE chunk for every reference to XXX
/// you can have 0 or more REFE chunks. Currently we work with
/// two versions of this chunk: the version wriXXXXXXXXX
/// </summary>
public class RefeChunk //: IffChunk //, IBinarySerializable
{
[FieldOrder(0)]
[FieldLength(4)]
public string ChunkName { get; set; }
[FieldOrder(1)]
[SerializeAs(Endianness = Endianness.Big)]
public UInt32 ChunkSize { get; set; }
[FieldOrder(2)]
[FieldLength("ChunkSize")]
[SerializeAs(Encoding = "UTF-8", Endianness = Endianness.Big)] //, SerializedType = SerializedType.ByteArray)]
public RefePayload RefePayload { get; set; }
//public byte[] RefePayload { get; set; }
[Ignore]
public int PadLength
{
get { return (ChunkSize % 2 == 0) ? 0 : 1; }
}
[FieldOrder(3)]
//[SerializeAs(SerializedType = SerializedType.ByteArray)]
//[FieldLength("PadLength")] //, ConverterType = typeof(PadHackConverter)]
//[SerializeAs(SerializedType = SerializedType.ByteArray)]
[SerializeWhen("PadLength", 1)]
//[FieldLength("PadLength")]
public byte Padding { get; set; } =0x00;
//
//public RefeChunk() : base("REFE")
//{
//}
//public void Serialize(Stream stream, Endianness endianness, BinarySerializationContext serializationContext)
//{
// throw new NotImplementedException();
//}
//public void Deserialize(Stream st, Endianness endianness, BinarySerializationContext serializationContext)
//{
// BinarySerializer bs = new BinarySerializer();
// EndianAwareBinaryReader br = new EndianAwareBinaryReader(st, Endianness.Big);
// bs.Endianness = Endianness.Big;
// this.ChunkName = new string(br.ReadChars(4));
// this.ChunkSize = br.ReadUInt32();
// this.ChunkVersion = bs.Deserialize<WankyVersion>(st);
// Debug.IndentLevel = 0;
// Debug.WriteLine(this.ChunkName + " size:" + this.ChunkSize + " " + this.ChunkVersion);
// this.RPV3= bs.Deserialize<RPV3>(st);
// this.DBV3= bs.Deserialize<DBV4>(st);
// byte B13 = br.ReadByte();
// this.Reserved13 = B13;
// Debug.WriteLineIf(this.Reserved13 != 13, "!!!!!!!!!!! RESERVED BYTE 13 iS BAD !!!!!!!!!!!! (SLAPS WRIST)");
// if (this.ChunkVersion >= this.MaxVersion)
// {
// Debug.WriteLine("REFE Chunk version is >= 1,3,0 so we are going to parse some more stuff...");
// //OTHER STUFF blah blah
// }
// //if odd size, read an extra byte
// if (ChunkSize % 2 != 0)
// {
// byte stubbbby = br.ReadByte();
// }
// //db
// //a
//}
Surely there is a way to avoid IBinarySerializer for such a simple concept, right?
