Extension method for checking regex in one line
This simple extension method allows you to check strings against regular expressions in one line.
using System;
using System.Text.RegularExpressions;
using System.Collections.Generic;

namespace TestRegex2342343
{
    class Program
    {
        static void Main(string[] args)
        {
            List<string> texts = new List<string>()
            {
                "233-2887",
                "2332887",
                "442-1121",
                "",
                null
            };

            foreach (var text in texts)
            {
                if (text.MatchesRegex("^[0-9]{3}-[0-9]{4}$"))
                    Console.WriteLine(text + " matches");
                else
                    Console.WriteLine(text + " does NOT match");
            }
            Console.ReadLine();
        }
    }

    public static class Helpers
    {
        public static bool MatchesRegex(this string text, string regex)
        {
            if (text == null || regex == null)
                return false;
            else
            {
                Match match = Regex.Match(text, regex);
                return match.Success;
            }
        }
    }
}
