这篇文章主要介绍了.net压缩功能实现方法,需要的朋友可以参考下
复制代码 代码如下:

public static class Compressor    {

            public static byte[] Compress(byte[] data)
            {
                using (MemoryStream output = new MemoryStream())
                {
                    using (GZipStream gzip = new GZipStream(output, CompressionMode.Compress, true))
                    {
                        gzip.Write(data, 0, data.Length);
                        gzip.Close();
                        return output.ToArray();
                    }
                }
            }

            public static byte[] Decompress(byte[] data)
            {
                using (MemoryStream input = new MemoryStream())
                {
                    input.Write(data, 0, data.Length);
                    input.Position = 0;
                    using (GZipStream gzip = new GZipStream(input, CompressionMode.Decompress, true))
                    {
                        using (MemoryStream output = new MemoryStream())
                        {
                            byte[] buff = new byte[64];
                            int read = -1;
                            read = gzip.Read(buff, 0, buff.Length);
                            while (read > 0)
                            {
                                output.Write(buff, 0, read);
                                read = gzip.Read(buff, 0, buff.Length);
                            }
                            gzip.Close();
                            return output.ToArray();
                        }
                    }
                }
            }
