谁有GZipStream 类压缩和解压缩字符串的列子
压缩结果是Stream也可以的。

------解决方案--------------------
顶一下.
public static byte[] CompressBytes(byte[] data)
{
ICSharpCode.SharpZipLib.Zip.Compression.Deflater f = new ICSharpCode.SharpZipLib.Zip.Compression.Deflater(ICSharpCode.SharpZipLib.Zip.Compression.Deflater.BEST_COMPRESSION);
f.SetInput(data);
f.Finish();

System.IO.MemoryStream o = new System.IO.MemoryStream(data.Length);

try
{
byte[] buf = new byte[1024];
while (!f.IsFinished)
{
int got = f.Deflate(buf);
o.Write(buf, 0, got);
}
}
finally
{
o.Close();
}
return o.ToArray();
}

public static byte[] DecompressBytes(byte[] data)
{
ICSharpCode.SharpZipLib.Zip.Compression.Inflater f = new ICSharpCode.SharpZipLib.Zip.Compression.Inflater();
f.SetInput(data);

System.IO.MemoryStream o = new System.IO.MemoryStream(data.Length);
try
{
byte[] buf = new byte[1024];
while (!f.IsFinished)
{
int got = f.Inflate(buf);
o.Write(buf, 0, got);
}
}
finally
{
o.Close();
}
return o.ToArray();
}

msdn上有现成的例子，还来问什么。
