本文實例講述了asp.net計算每個頁面執行時間的方法。。具體分析如下：

這里的asp.net代碼可實現計算每個頁面的執行時間，無需要修改頁面的相關代碼，這段代碼會給所有的頁面統一加上執行時間顯示

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 */ }}

希望本文所述對大家的asp.net程序設計有所幫助。
