Validating UK phone number (Regex C#)

Question

public static bool ValidatePhoneNumber(string number)
{
    return Regex.Match(number, \"^(\\+44\\s?7\\d{3}|\\(?07\\d{3}\\)?)\\s?\\d{3}\\s?\\d{3}$\", RegexOptions.Ignore         


        

Answer 1

Try using this:

^(\+44\\s?7\\d{3}|\(?07\\d{3}\)?)\\s?\\d{3}\\s?\\d{3}$

In order for the regex to recognize the \s, \d, etc you need to put double slash \\. If not you'll get an illegal escape character error.
