单声道放气流 [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 读取时，我有以下内容:

And when reading from ds2, i have the following:

这个问题出现在 Mono 2.6.1 &2.6.3...

This problem appears in Mono 2.6.1 & 2.6.3...

是否有任何已知的方法可以在 Mono 中成功读取 DeflateStream?或者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 在本机调用 zlib.
如果您使用的是 Unix 平台，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.
