Is extending String class with IsNullOrEmpty confusing?

Question

Everyone knows and love String.IsNullOrEmpty(yourString) method.

I was wondering if it\'s going to confuse developers or make code better if we extend String class t

Answer 1

Calling a method on a variable that is null usually results in a NullReferenceException. The IsNullOrEmpty()-Method deviates from this behaviour in a way that is not predictable from just looking at the code. Therefore I would advise against using it since it creates confusion and the benefit of saving a couple of characters is minimal.
