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。
