在asp.net文件下载之后就再也没有回传 [英] no more postback after file download in asp.net

问题描述

从网页下载文件后，我不能这样做网页上任何东西。它像网页无法工作了。当我点击另一个按钮，没有回发。

After downloading a file from a webpage, I can't do anything on that page. It is like the page is not working anymore. When I click on other button, there is no post back.

下面是我的代号。

filename= "test.txt"
Response.AppendHeader("content-disposition", "attachment; filename= " + fileName);
Response.WriteFile(Server.MapPath("~/" + fileName));
Response.End();

所以我试评到Response.End（）但它仍然没有工作。

还有什么能可能出现的问题？

What can be the possible problems?

推荐答案

尝试使用 Response.BinaryWrite（字节[]）方法。

filename= "test.txt";
byte []bytes=System.IO.File.ReadAllBytes(MapPath("~/" + filename));
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Type","application/octet-stream");
Response.AddHeader("Content-Length",bytes.Length.ToString());
Response.AddHeader("content-disposition", "attachment; filename= " + fileName);
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
