C#壓縮和解壓縮字節數組

 //壓縮字節
    //1.創建壓縮的數據流 
    //2.設定compressStream為存放被壓縮的文件流,並設定為壓縮模式
    //3.將需要壓縮的字節寫到被壓縮的文件流
    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();
        }
    }

    //解壓縮字節
    //1.創建被壓縮的數據流
    //2.創建zipStream對象，並傳入解壓的文件流
    //3.創建目標流
    //4.zipStream拷貝到目標流
    //5.返回目標流輸出字節
    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();
                }
            }
        }
    }
