How to convert a pdf to a memory stream

Question

I am writing an application in MVC4.

I have a physical pdf file on the server. I want to convert this to a memory stream and send it back to the user like this:

Answer 1

Worked it out

 var pdfContent = new MemoryStream(System.IO.File.ReadAllBytes(imageLocation));
                pdfContent.Position = 0;
                return new FileStreamResult(pdfContent, "application/pdf");

Answer 2

Use an overload that uses a filename, see here. It's the easiest solution when you have a physical file.

Answer 3

You don't need MemoryStream. Easiest way is to use overload that accepts file name:

return File(@"C:\MyFile.pdf", "application/pdf");

another solution is to use overload that accepts byte[]:

return File(System.IO.File.ReadAllBytes(@"C:\Myfile.pdf"), "application/pdf");

or if you want use FileStream:

return File(new FileStream(@"C:\MyFile.pdf", FileMode.Open, FileAccess.Read), "application/pdf");
