c#压缩和解压缩
--1.ClassBinary
1 public class ClassBinary 2 { 3 public ClassBinary() 4 { 5 // 6 // TODO: 在此处添加构造函数逻辑 7 // 8 } 9 /// <summary> 10 /// 压缩 11 /// </summary> 12 /// <param name="ds"></param> 13 /// <returns></returns> 14 public byte[] CompressToBytes(DataSet ds) 15 { 16 DataSetSurrogate dss = new DataSetSurrogate(ds); 17 BinaryFormatter ser = new BinaryFormatter(); 18 MemoryStream ms = new MemoryStream(); 19 ser.Serialize(ms, dss); 20 byte[] buffer = ms.ToArray(); 21 byte[] zipBuffer = new CompressionHelper(CompressionLevel.BestSpeed).CompressToBytes(buffer); 22 23 return zipBuffer; 24 } 25 /// <summary> 26 /// 解压 27 /// </summary> 28 /// <param name="zipBuffer"></param> 29 /// <returns></returns> 30 public DataSet DecompressToBytes(byte[] zipBuffer) 31 { 32 if (zipBuffer == null) return null; 33 byte[] buffer = new CompressionHelper().DecompressToBytes(zipBuffer); 34 BinaryFormatter ser = new BinaryFormatter(); 35 DataSetSurrogate dss = ser.Deserialize(new MemoryStream(buffer)) as DataSetSurrogate; 36 DataSet dsZip = dss.ConvertToDataSet(); 37 38 return dsZip; 39 } 40 41 }
2.使用
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);
