Lzma2 - Compress Error

My code:
_zipEncode = new SevenZipCompressor(); _zipEncode.TempFolderPath = _workingDir; _zipEncode.ArchiveFormat = OutArchiveFormat.SevenZip; _zipEncode.CompressionMode = CompressionMode.Create; _zipEncode.CompressionMethod = CompressionMethod.**Lzma2**; _zipEncode.CompressionLevel = CompressionLevel.Ultra;

If I set the parameters (Lzma2) SevenZipSharp does not work.
Creates an archive file size 32 Baity and break operation.

Lzma working properly.

Add support for RAR v5.0

Currently RAR5 is not supported by SevenZipSharp, I had a look at #11 and thought it might be a quick thing to add, but the problem is that both RAR4 and RAR5 use the .rar extension, so to add RAR5 it seems you'd have to overwrite RAR4 (and I can't find any mention on whether or not you can open a RAR4 file the same way as a RAR5 file).

In theory what's needed is to change /SevenZip/Formats.cs:

• Add/change the RAR5 GUID 23170f69-40c1-278a-1000-000110CC0000.
• Add/change its signature: 52-61-72-21-1A-07-01-00.

But the file extension confuses me, you can't add two duplicate extensions to InExtensionFormats.

Taking over maintenance?

Hi @tomap,

Since it seems there's no rush to take on this repo, I could do it - admittedly I'm not very familiar with it, but hopefully it's not worse than having it abandoned.

I updated my fork and pushed my PR for RAR5 support to it.

Let me know what else you need.

CommonDispose in SevenZipExtractor

Line 763, 764 is,

_inStream.Dispose();
_inStream = null;

When I use this class, _inStream is set null, so the error is occured at above lines,
Why don't you check _instream is null?

FreeLibrary calls

Hello,

I have a feeling this is the only SevenZipSharp project with commits within the last months.

Why does the SevenZipSharp free the 7z.dll after many compress operations?

I think it's a huge performance issue when creating many archives in a row.

Best regards

Extracting password a protected file from within a Non-password protected archive

Just wanted to see this this fork has the ability to extract a password protected file from within a non-password protected archive? The current version of Sevenzipsharp does not appear to have this functionality when using (extractor.ExtractFile(extractor.ArchiveFileData[i].FileName, st).

What LGPL License version is to be used?

The readme reads that the project is under the LGPL v3.0.
But the license.txt is showing LGPL v2.1. It looks like the license.txt should be updated.
Which one is it meant to be?

Kim

Hello, how to test if the compression package is damaged

I have a zip format compression package, use winrar software to open the prompt damage, but with SevenZipSharp can get the file information inside the compression package, and will not throw an exception, how to use SevenZipSharp to check whether the compression package is damaged? The test files are as follows:
