c#压缩和解压缩

public DataSet DecompressToBytes(byte[] zipBuffer)

if (zipBuffer == null) return null;
byte[] buffer = new CompressionHelper().DecompressToBytes(zipBuffer);
BinaryFormatter ser = new BinaryFormatter();
DataSetSurrogate dss = ser.Deserialize(new MemoryStream(buffer)) as DataSetSurrogate;
DataSet dsZip = dss.ConvertToDataSet();

return dsZip;
}

}

1、压缩
DataSet ds = new DataSet();//假设的ds
byte[] byte = new ClassBinary().CompressToBytes(ds );

2、解压缩
DataSet ds2 =new ClassBinary().DecompressToBytes(byte);
