C# 4.0: Convert pdf to byte[] and vice versa

How do I convert a pdf file to a byte[] and vice versa?

Answer Source
// loading bytes from a file is very easy in C#. The built in System.IO.File.ReadAll* methods take care of making sure every byte is read properly.
byte[] bytes = System.IO.File.ReadAllBytes("myfile.pdf");

// munge bytes with whatever pdf software you want, i.e. http://sourceforge.net/projects/itextsharp/
// bytes = MungePdfBytes(bytes); // MungePdfBytes is your custom method to change the PDF data
// ...
// make sure to cleanup after yourself

// and save back - System.IO.File.WriteAll* makes sure all bytes are written properly.
System.IO.File.WriteAllBytes("myfile.pdf", bytes);
