net实现压缩功能

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(); } } } }
