web regularexpressi on not working in windows

[Greg]

Standar 9-digit postal code expression, copied and pasted from a web
form validator expression:

@"\d{5}(-\d{4})?

I try to use it to validate a windows textbox, but it does not like
the '?'.
If the first part is matched,it doesnt care what comes afterwards.
Removing the ? gives proper behavior.

Can anyone please tell me why this is works on an asp page but not
with the Regex class?

Thanks,
Greg

Greg,

It may just be a typo, but are you sure the leading @" is part of the
regex? I tested the regex \d{5}(-\d{4})? on my system and it worked
fine.

Thanks Chris,

Actually found out today that I needed the $ to mark the end of the
string even though i knew the length. I just cut and paste the
expression from the asp regularexpressi onvalidator combo, but the ^ and
$ must be prepended to those expressions.

Thanks for your help

Greg
