.NET序列化和還原序列化

實踐是檢驗真理的唯一標準，看下面的代碼：

//序列化和還原序列化的測試
//構造測試資料,一個DataTable
System.Data.DataTable dt = new DataTable();
dt.Columns.Add("Id",System.Type.GetType("System.Int32"));
dt.Columns.Add("Name",System.Type.GetType("System.String"));

DataRow dr1 = dt.NewRow();
dr1["Id"] = 1;
dr1["Name"] = "atao";
dt.Rows.Add(dr1);

DataRow dr2 = dt.NewRow();
dr2["Id"] = 2;
dr2["Name"] = "tommy";
dt.Rows.Add(dr2);

//序列化
IFormatter formatter = new SoapFormatter();
System.IO.FileStream fs = new System.IO.FileStream("d:/test.xml",
                                                                             System.IO.FileMode.Create,
                                                                             System.IO.FileAccess.Write,
                                                                             System.IO.FileShare.None);
formatter.Serialize(fs,dt);
fs.Close();


//還原序列化
IFormatter formatter_d = new  SoapFormatter();
System.IO.FileStream fs_d = new System.IO.FileStream("d:/test.xml",
                                                                                 System.IO.FileMode.Open,
                                                                                 System.IO.FileAccess.Read,
                                                                                 System.IO.FileShare.None);

DataTable dtt = (DataTable)formatter_d.Deserialize(fs_d);

this.DataGrid1.DataSource = dtt.DefaultView;
this.DataGrid1.DataBind();

要更換序列化方式，只需把formatter更換就可以了。比如：IFormatter formatter_d = new  BinaryFormatter();
