Extract many phone numbers using RegEx

Question

I want to extract phone numbers from following regex. It extracts all phone number formats when I input numbers one by one but not when I input 2 or more numbers in one string.

@"^\+?(\d[\d-. ]+)?(\([\d-. ]+\))?[\d-. ]+\d$";

Answer 1

Of course it won't extract multiple numbers. The expression starts with ^ and ends with $ , so if the string contains anything other than a single phone number, the regular expression will fail to match.

One solution is to remove those start and end characters, and then loop to extract the numbers one at a time.

Regex rePhone = new Regex(@"\+?(\d[\d-. ]+)?(\([\d-. ]+\))?[\d-. ]+\d");
Match m = rePhone.Match(inputString);
while (m.Success)
{
    string phone = m.Value;
    m = m.NextMatch();
}

Answer 2

试试这个模式：

((\+\s|\d{1}\s?\+||\()(\d\)?\s?[-\.\s\(]??){8,}\d{1}|\d{3}[-\.\s]??\d{3}[-\.\s]??\d{4}|\(\d{3}\)\s*\d{3}[-\.\s]??\d{4}|\d{3}[-\.\s]??\d{4})
