Moved from OP's "solution":
[Edit]

C#
namespace _11_RegularExpressions
{
    class Class1
    {
        [STAThread]
        static void Main(string[] args)
        {
            Regex phoneExp = new Regex(@"^(234[7|8][0|1][2-9])([0-9]{7}$");
            string input;
            Console.Write("Enter a phone number: ");
            input = Console.ReadLine();
            while (phoneExp.Match(input).Success == false)
            {
                Console.WriteLine("Invalid input. Try again.");
                Console.Write("Enter a phone number: ");
                input = Console.ReadLine();
            }
            Console.WriteLine("Validated!");

Your solution is to pick up your C# textbooks and read them. Then write some code. When that code has bugs, ask us regarding those bugs and we'll be glad to help you. We will NOT do your homework for you.
