Try with this: @"^([+]?\d{1,2}[.\-\s]?)?(\d{3}[.-]?){2}\d{4}$" — robert

So just use your regex string pattern as is in C#, keeping in mind that C# does not support regex literals. — Wiktor Stribiżew

Remove '/' at the start and the end of the string.

Regex.Match(yourline, @"^([+]?\d{1,2}[.\-\s]?)?(\d{3}[.-]?){2}\d{4}$");

Doesn't work: 'RegExParseException: Invalid Pattern'. @robert's answer in the comments above is correct

Oops, I forgot to escape the '-' character. Updated it.

I'm guessing you didn't actually try it, but it's right now :-)

No, I did not. ;p
