Specifying filename for dynamic PDF in asp.net

Question

How can I specify the filename when dumping data into the response stream?

Right now I'm doing the following:

byte[] data= GetFoo();
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";            
Response.BinaryWrite(data);
Response.End();

With the code above, I get "foo.aspx.pdf" as the filename to save. I seem to remember being able to add a header to the response to specify the filename to save.

Answer 1

Response.AppendHeader("Content-Disposition", "attachment; filename=foo.pdf");

Answer 2

Add a content-disposition to the header:

Response.AddHeader("content-disposition", "attachment;filename=MyFile.pdf");

Answer 3

 Response.AddHeader("Content-Disposition", "attachment;filename=" & FileName & ";")
