获取页面加载时间（修改）

1.在Global.asax中添加如下

  DateTime dt;
   protected void Application_BeginRequest(Object sender, EventArgs E)
   {
       dt = DateTime.Now;
   }
   protected void Application_EndRequest(Object sender, EventArgs E)
   {

       DateTime dt2 = DateTime.Now;
       TimeSpan ts = dt2 - dt;
       Response.Write("页面加载的时间" + ts.TotalMilliseconds.ToString() + " 毫秒");
   }

在.cs页面加入如下

 DateTime dt;
    protected void onPreInit(EventArgs e)
    {
        dt = DateTime.Now;
    }
    protected void onLoadComplete(EventArgs e)
    {
        TimeSpan ts = DateTime.Now - dt;
        Response.Write("加载页面用时：" + ts.TotalMilliseconds);
    }
