asp.net计算每个页面执行时间的方法

　　本文标签：asp.net,页面,执行时间

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();
   // Dont 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 。
