a simple one for the Regex-perts =)

my regex for matching phone #'s:
\({0,1}(?<areac ode>[0-9]{3})\){0,1}( |-){0,1}(?<prefix >[0-9]{3})(
|-){0,1}(?<suffix >[0-9]{4})

which i then .Replace to become:
(${areacode}) ${prefix}-${suffix}

question: how do i fix the match regex so that it 'stops' after the suffix
of the phone # is matched? right now, it will return '(800) 555-1212345' if
i type in '8005551212345' - i just want '[phone]'.

as always, any help would be much appreciated! thanks!

I am no RegEx[pert] :-) but I think you have to join your groups as one.
What is happening is that your <suffix> group is being repeated because
[0-9]{4} can be found twice in 12121234, see: [1212] and [1234]. If you can
join the entire expression as a single group, I think that /may/ fix your
problem.

Regex.Replace simply replaces the matched text with the replacement string.
The expression only matches '8005551212', so it replaces that with '(800)
555-1212'. The '345' does not participate in the match, so it is left
alone. If you want it to go away, you need to make it part of the match and
then just leave it out of the replacement. Simply add '.*' to the end of
your regex to match whatever is left over after the number is matched:

\({0,1}(?<areac ode>[0-9]{3})\){0,1}( |-){0,1}(?<prefix >[0-9]{3})(
|-){0,1}(?<suffix >[0-9]{4}).*
