Json deserialization of null primitive types

Hi @enne30!

Just change type of koInt to int? (or Nullable<int>). Error happens because int is value type which is not allowing null as value. So you need a nullable int instead.

P.s. if your fields/properties of you class named same as in JSON you don't need DataMember and DataContract attributes.

public class Element
{
    public string okInt;
    public int? koInt;
}

They needed if you rename your fields/properties. For example:

[DataContract]
public class Element
{
    [DataMember(Name = "okInt")]
    public string MyField1;
    [DataMember(Name = "koInt")]
    public int? MyField2;
}

Thank you for quick reply and for letting me know this notation. 👍
