Question

I’m downloading an excel file within C# action method the reutrns a FileResult, like this:

return File(bindata, "application/octet-stream", "mytestfile.xls");

When I manually navigate to the URL that corresponds with the above method, then I get the rendered out representation of the file. The file will not download with a Save As -dialog.

Is there a way to force the download to happen through Save As -dialog?

Answer 1

I have a feeling you are getting this behavior because of the media type you are returning.

Try changing the media type to application/vnd.ms-excel like this:

return File(bindata, "application/vnd.ms-excel", "mytestfile.xls");
