Question

My words (phone numbers) may have in the beginning “00” or “+”.

Example number phone:

00xxx xx xxxxxxx
+xxx xx xxxxxxx
(+xxx) xx xxxxxxx
(00xxx) xx xxxxxxx

I have:

Regex regexObj = new Regex(@"^\(?[+( ]?([0-9]{3})\)?[) ]?([0-9]{2})[- ]?([0-9]{7})$");

if (regexObj.IsMatch(TextBox1.Text))
{
    // IF OK
    string formattedPhoneNumber = regexObj.Replace(TextBox1.Text, "(+$1) $2 $3");
}

How to put it in the regular expression? For now I can only put the “+”, and “(” , “)”

thanks

Answer 1

how about this:

Regex regexObj = new Regex(@"^(?:\(?)(?:\+|0{2})([0-9]{3})\)? ([0-9]{2}) ([0-9]{7})$");

EDIT:

^(?:\((?:\+|00)([0-9]{3})\)|(?:\+|00)([0-9]{3}))? ([0-9]{2})[- ]?([0-9]{7})$
