重定向到另一个页面到Response.End（）已经在C＃中被调用后 [英] Redirecting to another page after Response.End() has been called in C#

问题描述

我导出一个gridview到excel，在Web应用程序中使用.NET 4.0，在页面加载和需要要生成的文件，然后重定向到调用页面的页面。我遇到的问题，因为我的代码导出到Excel如下：

  gvSummary.Style.Add（FONT-SIZE ，.6em）; 
 Response.Clear（）; 
带安装=附件;文件名= filename.xls; 
 Response.ClearContent（）; 
 Response.AddHeader（内容处置，附件）; 
 Response.ContentType =应用程序/ vnd.openxmlformats-officedocument.spreadsheetml.sheet 
 StringWriter的SW =新的StringWriter（）; 
的HtmlTextWriter HTW =新的HtmlTextWriter（SW）; 
 gvSummary.GridLines = GridLines.Horizo​​ntal; 
 gvSummary.RenderControl（HTW）; 
的Response.Write（sw.ToString（））; 
到Response.End（）; 
  

我知道，如果我把的Response.Redirect（）的.END（）之前，我会重定向但从未产生的文件，如果我把的Response.Redirect（）的.END（）后我得到的文件，但没有重定向。

上面写的代码在生成文件就好了，但是当生成文件后，我仍然坚持看我的加载动画，因为我不能打出来的页。任何想法？

解决方案

我建议增加一个重定向头。事情是这样的：

  Response.AddHeader（刷新，3; URL =的index.html）; 
  

在哪里3是延迟和index.html的时间就是你需要重定向到

I am exporting a gridview to excel, using .Net 4.0 in a web application, on page load and need for the file to be generated and then the page to be redirected to the calling page. I am running into issues because my code to export to excel is as follows:

gvSummary.Style.Add("font-size", ".6em");
    Response.Clear();
    string attachment = "attachment; filename=filename.xls";
    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    StringWriter sw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(sw);
    gvSummary.GridLines = GridLines.Horizontal;
    gvSummary.RenderControl(htw);
    Response.Write(sw.ToString());
    Response.End();

I know that if I put the Response.Redirect() before the .End(), I will get redirected but the file is never generated, and if I put the Response.Redirect() after the .End() I get the file but no redirection.

The code written above works just fine in generating the file, however when after the file is generated I am still stuck seeing my Loading animation because I can not break out of the page. Any ideas?

解决方案

I suggest to add a redirect header. Something like this:

Response.AddHeader("Refresh", "3; url=index.html");

Where 3 is time of the delay and index.html is url you need to redirect to
