Why doesn't this RegEx match the phone number? How to fix?

Question

I have this phone number: +44 (0) 1234 123456

which the following regex is attempting to validate, but fails:

var regexPhone = new Regex(@"^(\\+)?([0-9\\s\\-])*$");

Can somebody tell me why it's failing? Is it possible to change this so that it will validate the number above?

Answer 1

Your regex does not allow any brackets.

See if Jabos's answer to this question can help you along.

Answer 2

我建议您使用The Regulator调试您的正则表达式。

Answer 3

As Jens pointed out, your regex does not allow brackets.

^(\+)((\([0-9\s\-]*\))|([0-9\s\-]))*$

This regex should work. It allows some digits to be inside brackets also.
