一段简单的代码

在Defalut.aspx.cs中给处理程序添加代码如下：

public partial class_Default:System.Web.UI.Page
{
    protected void buttonSubmit_Click(object sender,EventArgs e)  
    {
     string selectedEvent = dropDownListEvents.SelectedValue;
     string firstname = textFirstname.Text;
     string lastname = textLastname.text;
     string email = textEmail.Text;
    
     labelResult.Text = firstname + "" + lastname + "selected the event " + selectedEvent ;
    }
}
