How to convert pdf to byte[] and vice versa?
+5
A:
byte[] bytes = System.IO.File.ReadAllBytes("myfile.pdf");
System.IO.File.WriteAllBytes("myfile.pdf", bytes);

A:
Easiest way:
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);
}
Or something along these lines...

You forgot to take care ot the return value of the Read method. You have to loop the reading and read until you actually get all the data.

@Guffa not quite, if you take a look I've used `stream.Length` that returns the length of the ENTIRE file stream, hence reading the file as a whole, not only as chunk of data.

@Paulo: You are missing the point. Even if you request the entire stream from the Read method, it doesn't have to read the entire stream. It will read one byte or more, and return how many bytes were actually read. If you ignore the return value of the Read method, you may only get part of the file.
