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

I always create an extension method for "HasContent()" which generally makes sense, follows the "positive" specifications, and saves on code bloat because I use it much more often than its counterpart:

public static bool HasContent(this string s) {
    return !string.IsNullOrEmpty(s);
}
