How do I convert a pdf file to a byte and vice versa?
// 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);
