如何使代码在Response.end之后执行 [英] how to make code execute after Response.end

问题描述

我的代码就是这样

HttpContext.Current.Response.Clear();
     HttpContext.Current.Response.ContentType = "application/pdf";
     HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + "name" + ".pdf");
     HttpContext.Current.Response.TransmitFile("~/media/pdf/name.pdf");
     HttpContext.Current.Response.End();
     if (FileExists("/media/pdf/name.pdf"))
     {
         System.IO.File.Delete("D:/Projects/09-05-2013/httpdocs/media/pdf/name.pdf");
     }

我要在浏览器中下载name.pdf，下载后我要删除该文件.但是代码执行会在

Here I want to download name.pdf in the browser, and after the download I want o delete that file.But the code execution stops at

HttpContext.Current.Response.End();

该行之后没有代码.因此我的删除功能不起作用.是否可以解决此问题?

no code after that line is executed.so my delete function is not working.Is there any work around for this issue?

推荐答案

HttpResponse.End (根据

HttpResponse.End (as per documentation) raises a ThreadAbortException and as you do no attempt to handle this your method exits.

我不确定为什么必须使用End()，但是可以将清理"代码放在finally语句中.

I'm not sure exactly why you must use End(), but you could put the "cleanup" code in a finally statement.
