建立内存表方法【备用】

建立内存表的方法：

 

        DataTable dt = new DataTable();
        dt.TableName = "内存表";//获取或设置表的名称
        DataColumn datac = new DataColumn();
        datac.Caption = "第一列";//获取或设置列的标题
        datac.ColumnName = "no1";
        DataColumn data2 = new DataColumn();
        data2.Caption = "第二列";
        data2.ColumnName = "no2";
        DataColumn datal = new DataColumn();
        datal.Caption = "第三列";
        datal.ColumnName = "no3";
        DataColumn[] cls=new DataColumn[3];
        cls[0] = datac;
        cls[1] = data2;
        cls[2] = datal;
        dt.Columns.AddRange(cls);
        DataRow row1 = dt.NewRow();//使用该方法来生成行对象
        row1[0] = "2000";
        row1[1] = "2003";
        row1[2] = "6003";
        dt.Rows.Add(row1);
        dt.AcceptChanges();//接受表的修改
        this.GridView1.DataSource = dt;
        this.GridView1.DataBind();

暂时保存一溜后用。
