set inline false or omit it. way the header attachment (instead of inline).

e.g (this sample downloads file in file system)

public filepathresult downloadpdf() {     var cd = new system.net.mime.contentdisposition     {         filename = "foo.pdf"         //inline = false //false or omit     };       response.appendheader("content-disposition", cd.tostring());     return file("~/files/somefile.pdf", "application/pdf"); } 

the header like: content-disposition:attachment; filename=foo.pdf

---

file name set - sample obtaining pdf file system because don't generate 1 on fly (so code fine byte result). key item return correct header attachment - can set manually

response.appendheader("content-disposition", "attachment; filename=" + pdffile); 

and not have use system.net.mime.contentdisposition. btw, pdffile variable string (you're using filename property)?

hth...
