The simplest way is using File.WriteAllBytes:
File.WriteAllBytes(fileName, data);
No need for opening streams, worrying about closing them properly etc - it does it all for you.
That's assuming data already contains the PDF document appropriately, of course. If you haven't already got a PDF, you'll need to tell us what's in the byte[]...

@ammadkhan: Then that's a *completely* different question. (There's no real conversion going on in this question, despite the way it's phrased. It's just about writing the existing PDF to disk.) – Jon Skeet Nov 12 '22 at 07:52

If the data is already known to be pdf, it's simple.
System.IO.FileStream stream = new System.IO.FileStream(path, System.IO.FileMode.Create);
stream.write(data, 0, data.Length);
stream.Close();
