C# HttpContext.Current.Response.AddHeader () NOT WORKING

本文关键字：NOT WORKING AddHeader HttpContext Current Response | 更新日期: 2023-09-27 18:03:01

I have a problem with downloading pdf files.

This is my code in c# :

     string file = HttpContext.Current.Server.MapPath("/FOLDER1/FOLDER2/test.pdf");
       HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment; filename='"{0}.pdf'"", "GGG"));
       HttpContext.Current.Response.WriteFile(file, false);
       HttpContext.Current.Response.End();

It seems like HttpContext.Current.Response.AddHeader("Content-Disposition , string.Format("attachment; filename='"{0}.pdf'"", "GGG"));" is not working.

Instead of downloading the file it displays something like this:

x��V}p��۽ۻ��7�%��.9H�| ��p+w��^B�Z* A��甶Z;��3L�-3-�X�S�t�#S�v:-�~�X�ZK��y�}/��}��}>~ϳ��$��E��7?��} ��p4:�z'��9��b;��X��pP~�+q�둰å| �{p}]"�'ӡ��&� ռ��#�~��H�9��}��̴��0 +u�mS�� �,��B/.�A��. x��<�dlls��Elp׷ɷa� ��]��vW_��n}'��ҁY2n�ar��N3VZ��٬t��6��.��Q�u��`s�� ^��-�+�*+ʙ�9�+�$åׯ��{��e�~>�<�|�/

I also tried to downlad an image but the problem remains.

Can someone help me please?

C# HttpContext.Current.Response.AddHeader () NOT WORKING

try something like that:

string file=HttpContext.Current.Server.MapPath("/FOLDER1/FOLDER2/test.pdf");
MemoryStream stream= new MemoryStream();
HttpResponse response = HttpContext.Current.Response;            
response.ClearContent();
response.Clear();
response.ContentType = "application/pdf";
response.AddHeader("Content-Disposition", string.Format("attachment; filename='"{0}.pdf'""));
using (FileStream fs = new FileStream(file, FileMode.Create, System.IO.FileAccess.Write))
 {
     stream.WriteTo(fs);
 }
 response.Flush();
 response.End();
