手動添加DataTable

[csharp] 
  
[csharp]
//創建DataTable  
  DataTable dt = new DataTable("zhaopian"); 
  //添加列 
  DataColumn dc1 = new DataColumn("id", Type.GetType("System.String")); 
  DataColumn dc2 = new DataColumn("wenti", Type.GetType("System.String")); 
  DataColumn dc3 = new DataColumn("zhaopianming", Type.GetType("System.String")); 
  dt.Columns.Add(dc1); 
  dt.Columns.Add(dc2); 
  dt.Columns.Add(dc3); 
 
  //添加值 
  DataRow dr = dt.NewRow(); 
  dr[0] = "1"; 
  dr[1] = "測試"; 
  dr[2] = "P123456.jpg"; 

然後將datatable 賦值給 Gridview

  this.dataGrid1.DataSource = dt;
