asp.net计算每个页面执行时间的方法_实用技巧_

 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("
Page Generated in "+ result_time)); response.Write("
"); } public void Dispose() { /* Not needed */ } }
