Mono & DeflateStream

I have 开发者_Go百科a simple code

byte[] buffer = Encoding.UTF8.GetBytes("abracadabra");
MemoryStream ms = new MemoryStream();
DeflateStream ds = new DeflateStream(ms, CompressionMode.Compress, false);
ms.Write(buffer, 0, buffer.Length);

DeflateStream ds2 = new DeflateStream(ms, CompressionMode.Decompress, false);
byte[]  buffer2 = new byte[ms.Length];
ds2.Read(buffer2, 0, (int)ms.Length);
Console.WriteLine(Encoding.UTF8.GetString(buffer2));

And when reading from ds2, i have the following:

Stacktrace:

This problem appears in Mono 2.6.1 & 2.6.3...

Is there any known way to successfully read from DeflateStream in Mono? Or maybe there are some third-party open-source assemblies with the same functionality?

You can call zlib natively using Interop with DllImport.
Only trick is to use the right size in the structures and to include the shared library in the LD_LIBRARY_PATH, if you are on a Unix platform.

Please file a bug against Mono. If you do so, it might get fixed in time for 2.6.4.
