public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//第一行
Label l1 = new Label();
l1.Text = "用户名 ";
TextBox t1 = new TextBox();
TableCell tr1_tc1 = new TableCell();
TableCell tr1_tc2 = new TableCell();
tr1_tc1.Controls.Add(l1);
tr1_tc2.Controls.Add(t1);
TableRow tr1 = new TableRow();
tr1.Cells.Add(tr1_tc1);
tr1.Cells.Add(tr1_tc2);


//第二行
Label l2 = new Label();
l2.Text = "密码 ";
TextBox t2 = new TextBox();
t2.TextMode = TextBoxMode.Password;
TableCell tr2_tc1 = new TableCell();
TableCell tr2_tc2 = new TableCell();
tr2_tc1.Controls.Add(l2);
tr2_tc2.Controls.Add(t2);

TableRow tr2 = new TableRow();
tr2.Cells.Add(tr2_tc1);
tr2.Cells.Add(tr2_tc2);

Button b1 = new Button();
b1.Text = "登录 ";
TableCell tr3_tc1 = new TableCell();
tr3_tc1.Controls.Add(b1);
TableRow tr3 = new TableRow();
tr3.Cells.Add(tr3_tc1);
Table1.Rows.Add(tr1);
Table1.Rows.Add(tr2);
Table1.Rows.Add(tr3);

//怎么添加Click事件 不知道 麻烦各位帮忙 随便给个获得 上面所填写的值的事件咯

}


}

[解决办法]
Button b1 = new Button();
b1.Text = "登录 ";
TableCell tr3_tc1 = new TableCell();

》》》


Button b1 = new Button();
b1.Click += new EventHandler(b1_Click); // 在这里
b1.Text = "登录 ";
TableCell tr3_tc1 = new TableCell();


// 事件处理程序
protected void b1_Click(object sender, EventArgs e)
{
// ...
}
[解决办法]
每个控件 都给一个ID

TextBox t1 = (TextBox)TableID.FindControl( "ID ");

这样就能找到控件了
然后就可以操作了啊
