C#压缩和解压缩字节数组

 //压缩字节
    //1.创建压缩的数据流 
    //2.设定compressStream为存放被压缩的文件流,并设定为压缩模式
    //3.将需要压缩的字节写到被压缩的文件流
    public static byte[] CompressBytes(byte[] bytes)
    {
        using (MemoryStream compressStream = new MemoryStream())
        {
            using (var zipStream = new GZipStream(compressStream, CompressionMode.Compress))
                zipStream.Write(bytes, 0, bytes.Length);
            return compressStream.ToArray();
        }
    }

    //解压缩字节
    //1.创建被压缩的数据流
    //2.创建zipStream对象，并传入解压的文件流
    //3.创建目标流
    //4.zipStream拷贝到目标流
    //5.返回目标流输出字节
    public static byte[] Decompress(byte[] bytes)
    {
        using (var compressStream = new MemoryStream(bytes))
        {
            using (var zipStream = new GZipStream(compressStream, CompressionMode.Decompress))
            {
                using (var resultStream = new MemoryStream())
                {
                    zipStream.CopyTo(resultStream);
                    return resultStream.ToArray();
                }
            }
        }
    }
