c# - Regex to match all us phone number formats

Question

First of all i would say i have seen many example here and googled but none found that matches all the condition i am looking for some match top 3 not below some inbetween. Kindly let me know how to put all of them in one place.

(xxx)xxxxxxx
(xxx) xxxxxxx
(xxx)xxx-xxxx

Using as :

  const string MatchPhonePattern =
           @"(?d{3})?-? *d{3}-? *-?d{4}";
            Regex rx = new Regex(MatchPhonePattern, RegexOptions.Compiled | RegexOptions.IgnoreCase);
            // Find matches.
            MatchCollection matches = rx.Matches(text);
            // Report the number of matches found.
            int noOfMatches = matches.Count;
            // Report on each match.

            foreach (Match match in matches)
            {

                tempPhoneNumbers= match.Value.ToString(); ;

             }
