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

Add a content-disposition to the header:

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

Answer 2

FYI... if you use "inline" instead of "attachment" the file will open automatically in IE. Instead of prompting the user with a Open/Save dialogue.

Response.AppendHeader("content-disposition", string.Format("inline;FileName=\"{0}\"", fileName));
