When downloading a file from ASP .Net, the text file gets appended with HTML content

Question

I have made a page that allows users to upload files to the server using a FileUpload Control and handling its event with this code

Sub SaveAttachment()
             


        

Answer 1

Is is not safe to use Response.End(), It will always return a System.Threading.ThreadAbortException:.. if debugged and seen in the catch block...

Alternative.. Use the following instead...

Response.Flush();
Response.SuppressContent = true;
Response.WriteFile(filepath);
HttpContext.Current.ApplicationInstance.CompleteRequest();
