Hi guys,

I use this code for a download function but when I run the code it displays what looks like a binary file that is opened in a text editor.

C#

public FileResult Download(int id)
        {
            byte[] fileBytes = System.IO.File.ReadAllBytes(Server.MapPath("~/Reports/Invoices/" + Table.Where(x => x.ID == id).FirstOrDefault().ID + ".pdf"));
            string fileName = Table.Where(x => x.ID == id).FirstOrDefault().ID.ToString();
            return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Pdf, fileName);
        }

Hi
Can you try with 'FileContentResult()' I.E. return new FileContentResult(....)

The reason this is not working is because I use ajax for the download link witch I am told will not work. I have no choice but to use ajax so is there any other way in witch I can do a file download

Solution 2

you must set the content type before returning the result to the user
return File(byte[], "application/zip", path + ".zip");

Solution 3

you must set the content type before returning the result to the user. Also, it is better to put the header by hand,

C#

not System.Net.Mime.MediaTypeNames.Application.Pdf

C#

return File(byte[], "application/zip", path + ".zip");
