c# - 匹配所有美国电话号码格式的正则表达式

Question

首先我会说我在这里看到了很多例子并用谷歌搜索但没有发现符合我正在寻找一些匹配前 3 名不低于某些中间值的所有条件。请告诉我如何将它们全部放在一个地方。

(xxx)xxxxxxx
(xxx) xxxxxxx
(xxx)xxx-xxxx
(xxx) xxx-xxxx
xxxxxxxxxx
xxx-xxx-xxxxx

用作:

  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(); ;

             }

示例输出:
