1.在ResultPage中添加：<%@ PreviousPageType VirtualPath="~/Registration.aspx" %>
这样之前ResultPage.aspx.cs中页面载入时间的代码则由：

 1 try
 2             {
 3                 DropDownList dropDownListEvents = (DropDownList)PreviousPage.FindControl("dropDownListEvents");
 4                 string selectedEvent = dropDownListEvents.SelectedValue;
 5 
 6                 string fistName = ((TextBox)PreviousPage.FindControl("textFirstName")).Text;
 7 
 8                 string lastName = ((TextBox)PreviousPage.FindControl("textLastName")).Text;
 9 
10                 string email = ((TextBox)PreviousPage.FindControl("textEmail")).Text;
11 
12                 labelResult.Text = String.Format("{0} {1} selected the event {2}", fistName, lastName, selectedEvent);
13             }
14             catch
15             {
16                 labelResult.Text = "The originating page must contain" + "textFirstName, textLastName, textEmail controls";
17             }

变为：

1 try
2             {
3                 RegistrationInfo ri = PreviousPage.RegistrationInfo;
4                 labelResult.Text = String.Format("{0} {1} selected the event {2}", ri.FirstName, ri.LastName, ri.SelectedEvent);
5             }
6             catch
7             {
8                 labelResult.Text = "The originating page must contain" + "textFirstName, textLastName, textEmail controls";
9             }
