GZIP的压缩与解压缩代码：
public static class CompressionHelper{/// <summary> /// Compress the byte[] /// </summary> /// <param name="input"></param> /// <returns></returns> public static byte[] Compress(byte[] input){byte[] output;using (MemoryStream ms = new MemoryStream()){using (GZipStream gs = new GZipStream(ms, CompressionMode.Compress)){gs.Write(input, 0, input.Length);gs.Close();output = ms.ToArray();}ms.Close();}return output;}/// <summary> /// Decompress the byte[] /// </summary> /// <param name="input"></param> /// <returns></returns> public static byte[] Decompress(byte[] input){List<byte> output = new List<byte>();using (MemoryStream ms = new MemoryStream(input)){using (GZipStream gs = new GZipStream(ms, CompressionMode.Decompress)){int readByte = gs.ReadByte();while (readByte != -1){output.Add((byte)readByte);readByte = gs.ReadByte();}gs.Close();}ms.Close();}return output.ToArray();}}
