How do i tell if a string obeys a regular expression?

i thought i knew but then i tried to verify that a string was a certain
length...

Regex.IsMatch("1234", @"\w{1,3}")

This returns true and i don't want it to!

i understand that it found *a* match - "123" matched \w{3}. But i don't care
if some substring matched, i want to know if the entire value matched

Help?

If you want to match the whole string then put '^' at the start and
'$' at the end of your regular expression. They match
start-of-string/line and end-of-string/line respectively. Your
example would become @"^\w{1,3}$"
