Http response file download not working in Internet explorer and chrome (C#, Asp.net)

Question

I write a file download method to download file from server to client machine in C# asp.net

I wrote the following code:

Response.ContentType = ReturnExtension(System.IO.Path.GetExtension(file.Name));

                    Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);

                    Response.TransmitFile(strRequest);

                    Response.End();

This will work fine in Firefox and Chrome, but not in IE.

Answer 1

在某些版本的IE中，我遇到了类似的问题，必须设置Cache-Control标头才能使下载正常进行：

response.Cache.SetCacheability(HttpCacheability.Private);

Answer 2

尝试将Response.Clear()放在代码之上。
