ds.Tables["stu"].Columns.Add("stuName", typeof(string));

ds.Tables["stu"].Columns.Add("stuScore", typeof(int));

ds.Tables["stu"].Rows.Add(new object[] { 1, "王聪", 100 });

ds.Tables["stu"].Rows.Add(new object[] { 2, "李宁", 100 });

ds.Tables["stu"].Rows.Add(new object[] { 3, "菡萏", 100 });

ds.Tables["stu"].Rows.Add(new object[] { 4, "青松", 100 });

//绑定到ListBox控件

this.ListBox1.DataSource = ds.Tables["stu"];

this.ListBox1.DataValueField = "stuNo";

this.ListBox1.DataTextField = "stuName";

TableRow tRow = new TableRow();

Table1.Rows.Add(tRow);

for (cellCount = 1; cellCount <= cellNum; cellCount++)

{

//创建单元格并添加到表中

TableCell tCell = new TableCell();

tRow.Cells.Add(tCell);

//添加一个用来包含文本的Literal类,作为控件添加到单元格中

tCell.Controls.Add(new LiteralControl("当前位置:"));

//创建一个Hyperlink控件并把它添加到单元格中

System.Web.UI.WebControls.HyperLink h = new HyperLink();
