ASP.NET MVC FileStreamResult, fileDownloadName is not used

Question

The following returns a PDF which the browser tries to directly display inline. This works correctly. However, if I try to download the file, the download name is not \"myPD

Answer 1

It is possible by making the id a string which represents the file name without the extension.

public ActionResult PDFGenerator(string id, int? docid)
{
    Stream stream = GeneratePDF(docid);
    return new FileStreamResult(stream , "application/pdf");
}

The url then then end like this

  ..PDFGenerator/Document2?docid=15
