单声道& DeflateStream [英] Mono & DeflateStream
问题描述
我有一个简单的代码
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));
从ds2中读取时，我有以下内容:
And when reading from ds2, i have the following:

此问题出现在Mono 2.6.1&中； 2.6.3 ...
This problem appears in Mono 2.6.1 & 2.6.3...
有没有已知方法可以成功从Mono中的DeflateStream读取?也许有一些具有相同功能的第三方开源程序集?
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?
推荐答案
您可以使用Interop和DllImport来原生调用zlib.
如果您是在Unix平台上，唯一的技巧是在结构中使用正确的大小，并将共享库包含在LD_LIBRARY_PATH中.
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.
