asp.net 页面执行耗时统计

在asp.net中计算页面执行所耗时间

 主要是重写 Render方法

DateTime  start; 
 
void  Page_Init  (Object  sender,  EventArgs  e) 
{ 
 start =  DateTime.Now; 
} 
protected  override  void  Render(HtmlTextWriter  writer) 
{ 
   base.Render(writer); 
 
   DateTime  stop  =  DateTime.Now; 
   Response.Write("done  in  "  +  (stop-start)); 
} 

方法二:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
   Application["StartTime"] = System.DateTime.Now;
}
protected void Application_EndRequest(Object sender, EventArgs e)
{
   System.DateTime startTime = (System.DateTime)Application["StartTime"];
   System.DateTime endTime = System.DateTime.Now;
   System.TimeSpan ts = endTime - startTime;
   Response.Write("页面执行时间:"+ ts.Milliseconds +" 毫秒");
  }

代码直接copy到Global.asax就可以运行了。
