c#添加动态点击事件

谢谢（：

为每个标签分配一次单击事件：

protected void l1_click(object sender, EventArgs e)
    {
        RegisterForm register = new RegisterForm(username,email,password,address,phone);
        register.state.Text = region;
        register.city.Text = l1[count].Text;
        register.Show();
    }

在click事件中，使用sender参数查看单击了哪个标签：

l1[count].Click += l1_click;

l1[count].Click += l1_click;

protected void l1_click(object sender, EventArgs e)
{
  Label lbl = (Label)sender;
  MessageBox.Show(lbl.Text);
