网页页面中调用方法：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Web;  
using System.Web.UI;  
using System.Web.UI.WebControls;

public partial class Admin\_Default : AdminPageBase   //把继承接口System.Web.UI.Page改为AdminPageBase  
\{  
    protected void Page\_Load(object sender, EventArgs e)  
    \{

\}  
\}
