如何使用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
