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

Question

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

Answer 1

// 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. // note that for Linux, you will not need the c: part // just swap out the example folder here with your actual full file path string pdfFilePath = "c:/pdfdocuments/myfile.pdf"; byte[] bytes = System.IO.File.ReadAllBytes(pdfFilePath);  // 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 - this will overwrite the file, if you don't want that, change the path here to something else System.IO.File.WriteAllBytes(pdfFilePath, bytes);
