復制代碼 代碼如下:

HiddenField hfOrderID = new HiddenField();
HiddenField hfPayMoney = new HiddenField();
if (Page.PreviousPage != null)
{
try
{　　
　　　　//
//查找母版頁 ,
MasterPage masterPage = (MasterPage)Page.PreviousPage.Controls[0];
//
//查找容器
ContentPlaceHolder contentPlaceHolder = (ContentPlaceHolder)masterPage.FindControl("ContentPlaceHolder3");
System.Web.UI.UserControl userControl = (System.Web.UI.UserControl)contentPlaceHolder.FindControl("MyOrder1");
//
//查找到對應的數據傳送HiddenField
hfOrderID = (HiddenField)userControl.FindControl("hfOrderID");
hfPayMoney = (HiddenField)userControl.FindControl("hfPayMoney");
　　　 //
//獲取傳入的訂單號
string strOrderID = hfOrderID.Value;
string strPayMoney = hfPayMoney.value;
　　}
}
