Converting Numbers to Words in C#

The program supports both the US and UK numbering systems. For example the number 620 would be expressed as follows:

    Six Hundred Twenty   (in the US system)

    Six Hundred and Twenty  (in the UK system)

Source Code

using System;

class Program

{

    static void Main()

    {

        string input;

        int number;

        bool isValid;

        bool isUK = false;

        Console.WriteLine("\nEnter '0' to quit the program at any time\n");

        while (true)

        {

            Console.Write("\nUse UK numbering y/n : ");

            input = Console.ReadLine();

            if (!(input.ToLower() == "y" || input.ToLower() == "n"))

                Console.WriteLine("\n  Must be 'y' or 'n', please try again\n");

            else

            {

                if (input.ToLower() == "y") isUK = true;

                Console.WriteLine("\n");

                break;

            }

        }

        do

        {

            Console.Write("Enter integer : ");

            input = Console.ReadLine();

            isValid = int.TryParse(input, out number);

            if (!isValid)

                Console.WriteLine("\n  Not an integer, please try again\n");

            else

                Console.WriteLine("\n  {0}\n", NumberToText(number, isUK));

        }

        while (!(isValid && number == 0));

        Console.WriteLine("\nProgram ended");

    }
