encryption - What's the easiest way to encrypt a file in c#?

Question

Beforehand :

I have read indeed the other topics on SO, but I can't find an answer in them.
(The others are about config-files, or a list of techniques)

My question thus is very simple, though a bit subjective (I'll label it beforehand :-)) what is the easiest way..

Answer 1

File.Encrypt is pretty simple - one call (with one parameter).

Of course, it really depends on what you want the encryption for. File.Encrypt encrypts to the current account, which isn't much use if you're passing the file around. But, given your spec - i.e. easiest way to encrypt a file - it has to be a candidate!
