Detect if a string contains uppercase characters

Question

Is there an alternative to using a regular expression to detect if a string contains uppercase characters? Currently I\'m using the following regular expression:

<         


        

Answer 1

Your regex will only find ASCII uppercase letters. Conveniently, the .NET regex engine is Unicode-aware, enabling you to do

Regex.IsMatch(fullUri, @"\p{Lu}") 

although I suppose that in your case you're not expecting non-ASCII letters in your string (considering its name).
