使用2.0中的压缩流减少网络传输量

public static byte[] Compress(DataSet ds)
{
BinaryFormatter ser = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
//Binary 作为二进制内容序列化。仅可在 ADO.NET 2.0 中使用
ds.RemotingFormat = SerializationFormat.Binary;
//序列化到MemoryStream
ser.Serialize(ms, ds);
//压缩后的MemoryStream
MemoryStream compressMs = new MemoryStream();
// 写入压缩的MemoryStream
GZipStream compressedStream = new GZipStream(compressMs, CompressionMode.Compress, true);
compressedStream.Write(ms.ToArray(), 0, ms.ToArray().Length);
return compressMs.ToArray();

}

public static DataSet Decompress(byte[] data)
{
MemoryStream unCompressMS = new MemoryStream();
MemoryStream compressMS = new MemoryStream(data);
GZipStream decompressedStream = new GZipStream(unCompressMS, CompressionMode.Decompress, true);
decompressedStream.Write(compressMS.ToArray(), 0, compressMS.ToArray().Length);
BinaryFormatter ser = new BinaryFormatter();
return (DataSet)ser.Deserialize(unCompressMS);
}

比较了一下,使用压缩与不使用压缩的有明显的优势,差不多是在十分之一的流量左右
