        List list = new List { 1, 2, 3, 4 }; // choices are in the list

        while (true)
        {
            Console.WriteLine("Please enter a number :");
            if (int.TryParse(Console.ReadLine(), out value))
            {
                if (list.Contains(value))
                    break;
            }
        }

        // value is in the list, deal with it.
