C# DataSet对象序列化并压缩

今天做一个项目中用到把DataSet对象序列化成文件，并上传到服务器，不过生成的文件比较大，就想着压缩一下，找了一下资料，用GZipStream来压缩了一下，效果还是非常理想的。现在把这部分代码整理了一下：

using System.Data;   using System.IO;   using System.IO.Compression;   using System.Runtime.Serialization;   using System.Runtime.Serialization.Formatters.Binary;     namespace DataSetSerializerDeserialize   {       class Program       {           /// <summary>           /// 序列化DataSet对象并压缩           /// </summary>           /// <param name="ds"></param>           static void DataSetSerializerCompression(DataSet ds)           {               IFormatter formatter = new BinaryFormatter();//定义BinaryFormatter以序列化DataSet对象                              MemoryStream ms = new MemoryStream();//建立内存流对象                 formatter.Serialize(ms, ds);//把DataSet对象序列化到内存流  

byte[] buffer = ms.ToArray();//把内存流对象写入字节数组                 ms.Close();//关上内存流对象                 ms.Dispose();//释放资源                 FileStream fs = File.Create("datasetCompression.dat");//建立文件                 GZipStream gzipStream = new GZipStream(fs, CompressionMode.Compress, true);//建立压缩对象                 gzipStream.Write(buffer, 0, buffer.Length);//把压缩后的数据写入文件                 fs.Close();//关上流                 fs.Dispose();//释放对象           }             /// <summary>           /// 不压缩直接序列化DataSet           /// </summary>           /// <param name="ds"></param>           static void DataSetSerializer(DataSet ds)  

 {               IFormatter formatter = new BinaryFormatter();//定义BinaryFormatter以序列化DataSet对象                 FileStream fs = File.Create("dataset.dat");//建立文件                 formatter.Serialize(fs, ds);//把DataSet对象序列化到文件                 fs.Close();//关上流                 fs.Dispose();//释放对象           }             static void Main(string[] args)           {               DataTable table = new DataTable("ParentTable");                              DataColumn column;               DataRow row;                 column = new DataColumn();               column.DataType = System.Type.GetType("System.Int32");   column.ColumnName = "id";               column.ReadOnly = true;               column.Unique = true;               table.Columns.Add(column);                 column = new DataColumn();               column.DataType = System.Type.GetType("System.String");               column.ColumnName = "ParentItem";               column.AutoIncrement = false;               column.Caption = "ParentItem";               column.ReadOnly = false;               column.Unique = false;               table.Columns.Add(column);                 DataColumn[] PrimaryKeyColumns = new DataColumn[1];  

PrimaryKeyColumns[0] = table.Columns["id"];               table.PrimaryKey = PrimaryKeyColumns;                 DataSet dataSet = new DataSet();               dataSet.Tables.Add(table);                 for (int i = 0; i <= 100; i++)               {                   row = table.NewRow();                   row["id"] = i;                   row["ParentItem"] = "ParentItem " + i;                   table.Rows.Add(row);               }               DataSetSerializer(dataSet);               DataSetSerializerCompression(dataSet);

     }       }   }
