lele通过本文主要向大家介绍了页面跳转 asp.net,阐述asp.net页面模型,js调用asp.net方法,asp.net,asp net培训等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
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 */ }
}
</div>
希望本文所述对大家的asp.net程序设计有所帮助。
