Find the inner-most exception without using a while loop?

Question

When C# throws an exception, it can have an inner exception. What I want to do is get the inner-most exception, or in other words, the leaf exception that doesn\'t have an i

Answer 1

Oneliner :)

while (e.InnerException != null) e = e.InnerException;

Obviously, you can't make it any simpler.

As said in this answer by Glenn McElhoe, it's the only reliable way.
