UC知道救命，asp.net压缩的问题！

我用下面的方法实现了压缩文件！
//文件流
FileStream reader;
reader = File.Open("D:\\foo.txt", FileMode.Open);
FileStream writer;
writer = File.Create("D:\\dest.gzip");
//压缩相关的流
MemoryStream ms = new MemoryStream();
GZipStream zipStream = new GZipStream(ms, CompressionMode.Compress, true);
//往压缩流中写数据
byte[] sourceBuffer = new byte[reader.Length];
reader.Read(sourceBuffer, 0, sourceBuffer.Length);
zipStream.Write(sourceBuffer, 0, sourceBuffer.Length);
//一定要在内存流读取之前关闭压缩流
zipStream.Close();
zipStream.Dispose();
//从内存流中读数据
ms.Position = 0; //注意，不要遗漏此句
byte[] destBuffer = new byte[ms.Length];
ms.Read(destBuffer, 0, destBuffer.Length);
writer.Write(destBuffer, 0, dest
//文件流
FileStream reader;
reader = File.Open("D:\\foo.txt", FileMode.Open);
FileStream writer;
writer = File.Create("D:\\dest.gzip");
//压缩相关的流
MemoryStream ms = new MemoryStream();
GZipStream zipStream = new GZipStream(ms, CompressionMode.Compress, true);
//往压缩流中写数据
byte[] sourceBuffer = new byte[reader.Length];
reader.Read(sourceBuffer, 0, sourceBuffer.Length);
zipStream.Write(sourceBuffer, 0, sourceBuffer.Length);
//一定要在内存流读取之前关闭压缩流
zipStream.Close();
zipStream.Dispose();
//从内存流中读数据
ms.Position = 0; //注意，不要遗漏此句
byte[] destBuffer = new byte[ms.Length];
ms.Read(destBuffer, 0, destBuffer.Length);
writer.Write(destBuffer, 0, dest
需要添加文件名信息的，我帮你改了一个
，winrar中测试可以
