C# 4.0: Convertir PDF a byte [] y viceversa

Question

¿Cómo convierto un archivo pdf en un byte [] y viceversa?

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. 
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); 

Answer 2

La manera más fácil:

byte[] buffer; 
using (Stream stream = new IO.FileStream("file.pdf")) 
{ 
    buffer = new byte[stream.Length - 1]; 
    stream.Read(buffer, 0, buffer.Length); 
} 

using (Stream stream = new IO.FileStream("newFile.pdf")) 
{ 
    stream.Write(buffer, 0, buffer.Length); 
} 

O algo en este sentido ...
