string.IsNullOrEmpty() vs string.NotNullOrEmpty()

Question

I\'m curious if any developers use string.IsNullOrEmpty() more often with a negative than with a positive

e.g.

if (!string.IsNullOrEmpty())

Answer 1

Because "IsNullOrEmpty" is easier to understand than "NotNullOrEmpty". The latter could be interpreted as:

1. It's not null and it's not empty
2. It's not null or it is empty
