asp.net计算每个页面执行时间的方法

本文实例讲述了asp.net计算每个页面执行时间的方法。分享给大家供大家参考。具体分析如下：

这里的asp.net代码可实现计算每个页面的执行时间，无需要修改页面的相关代码，这段代码会给所有的页面统一加上执行时间显示

public class performancemonitormodule : ihttpmodule
{
 public void init(httpapplication context)
 {
  context.prerequesthandlerexecute += delegate(object sender,eventargs e)
  {
   //set page timer star
   httpcontext requestcontext = ((httpapplication)sender).context;
   stopwatch timer = new stopwatch();
   requestcontext.items["timer"] = timer;
   timer.start();
   };
  context.postrequesthandlerexecute += delegate(object sender, eventargs e)
  {
   httpcontext httpcontext = ((httpapplication)sender).context;
   httpresponse response = httpcontext.response;
   stopwatch timer = (stopwatch)httpcontext.items["timer"];
   timer.stop();
   // don't interfere with non-html responses
   if (response.contenttype == "text/html")
   {
    double seconds = (double)timer.elapsedticks / stopwatch.frequency;
    string result_time = string.format("{0:f4} sec ", seconds);
    renderqueriestoresponse(response,result_time);
   }
  };
 }
 void renderqueriestoresponse(httpresponse response, string result_time)
 {
  response.write("<div style=\"margin: 5px; background-color: #ffff00\"");
  response.write(string.format("<b>page generated in "+ result_time));
  response.write("</div>");
 }
 public void dispose() { /* not needed */ }
}

希望本文所述对大家的asp.net程序设计有所帮助。
