regular expression pattern needed

[Craig Buchanan]

I need to strip the ()- and spaces from a telephone number. What is the
regular express pattern for this? "\(\)-"?

thanks

Try this:

PhoneNumber = Regex.Replace(PhoneNumber, "[()-]","")

that works. this too:

'strip anything that isn't a number
PhoneNumber = Regex.Replace(PhoneNumber, "[^0-9]","")

Try this:

PhoneNumber = Regex.Replace(PhoneNumber, "[()-]","")

Craig,
Which can be shorted to:

'strip anything that isn't a number
PhoneNumber = Regex.Replace(PhoneNumber, "\D","")

However, yours & mine will clobber phone numbers that are words:

1-800-FOR-HELP

Hope this helps

Craig,

What does the \D mean?

"\D" effectively means "[^0-9]"

Per:
http://msdn.microsoft.com/library/d...en-us/cpgenref/html/cpconCharacterClasses.asp

\D : Matches any nondigit. Equivalent to \P{Nd} for Unicode and [^0-9] for
non-Unicode, ECMAScript behavior.

Most of the time I prefer the character codes \d over [0-9] or \D over
[^0-9] as they are more internationalized (they will work for any Unicode
numeric value, not just the ANSI 0 to 9 characters. Also they tend to be
shorter ;-)

Hope this helps
Jay
