C#中如何解压gzip压缩后的字符流?

[qugui]

我现在得到一网页返回的流是gzip压缩的,我想要解压后显示原来的内容,请高手赐教.

using ICSharpCode.SharpZipLib.GZip;

public static byte[] Compress(Stream Source)
{
Debug.Assert(null != Source);
Source.Seek(0, SeekOrigin.Begin);
MemoryStream objMem = new MemoryStream();
GZipOutputStream objGzip = new GZipOutputStream(objMem);

const int BUFFER_SIZE = 1024 * 10;
byte[] arrBuffer = new byte[BUFFER_SIZE];
int nGetedCount = 0;
do
{
nGetedCount = Source.Read(arrBuffer, 0, BUFFER_SIZE);
objGzip.Write(arrBuffer, 0, nGetedCount);
} while(nGetedCount>0);
objGzip.Finish();
byte[] arrResult = objMem.ToArray();
objGzip.Close(); //压缩完成后，输出流就会被关闭
objGzip = null;
objMem.Close();
objMem = null;
return arrResult;
}

你们说的不行呀,的到的数据在IE里面可以解开,但在程序里解不开.
