Solution 3

Try this:

using System;
using System.Text.RegularExpressions;

public class Program
{
	public static void Main()
	{
		Regex regex = new Regex(@"^\d{3}-\d{3}-\d{4}$|^\(\d{3}\)\d{3}-\d{4}$|^\d{10,11}$");
		Match match = regex.Match("11122212345");
		if (match.Success)
		{
			Console.WriteLine(match.Value);
		}
	}
}
