hay,
this will return true,

 string phoneNumber = "444-6666";
 bool val = System.Text.RegularExpressions.Regex.IsMatch(phoneNumber, "^[0-9,()+-]{8,12}$");

if you just write the formula that you want for the phone i think i can help

Hey,

Check the link in my signature, there are a number of Regex related links in it.

Specifically, Regex Lib, it has a own library of Regular Expressions, so it is likely that you will find the one that you need there.

Hope that helps!
