DataSet ds=new DataSet();
            DataTable tableEmp=new DataTable("employee");
            tableEmp.Columns.Add("ID",typeof(int));
            tableEmp.Columns.Add("Name",typeof(string));
            ds.Tables.Add(tableEmp);
                            //从这里开始如何写个循环，而不用写成下面这么复杂？
            DataRow row1=tableEmp.NewRow();
            row1["ID"]=0001;
            row1["Name"]="Joe Users";
            tableEmp.Rows.Add(row1);
            DataRow row2=tableEmp.NewRow();
            row2["ID"]=0002;
            row2["Name"]="A2";
            tableEmp.Rows.Add(row2);
            DataRow row3=tableEmp.NewRow();
            row3["ID"]=0003;
            row3["Name"]="A1";
            tableEmp.Rows.Add(row3);
            DataRow row4=tableEmp.NewRow();
            row4["ID"]=0003;
            row4["Name"]="AAA";
            tableEmp.Rows.Add(row4);
            this.DataGrid1.DataSource=ds;
            this.DataGrid1.DataBind();

如何写一个row1-row4的循环啊？
