중첩 된 switch 문을 사용하여 숫자를 0-9999 범위의 단어로 변환하는 방법

그래서 수백 개까지만 변환하는이 코드를 수정 해 보았습니다.

class Program

    static void Main(string[] args)

        Console.Write("Enter a number between 0 and 9999: ");
        short number = Convert.ToInt16(Console.ReadLine());

        byte thousandths = (byte)(number / 1000 | 0);
        byte hundreds = (byte)(number / 100 | 0);
        byte tensAndOnes;

        if (number > 99)
        {
            tensAndOnes = (byte)(number % 100);
        }
        else tensAndOnes = (byte)(number * 1);

        byte ones = (byte)(number % 10);

        switch (thousandths)
        {
            case 1: Console.Write("One thousand "); break;

        else if (tensAndOnes >= 70 && tensAndOnes < 80) Console.Write("Seventy");
        else if (tensAndOnes >= 80 && tensAndOnes < 90) Console.Write("Eighty");
        else if (tensAndOnes >= 90 && tensAndOnes < 100) Console.Write("Ninety");

        switch (tensAndOnes)
        {
            case 1: Console.Write("One"); break;
            case 2: Console.Write("Two"); break;
            case 3: Console.Write("Three"); break;

            case 10: Console.Write("Ten"); break;
            case 11: Console.Write("Eleven"); break;
            case 12: Console.Write("Twelve"); break;
            case 13: Console.Write("Thirteen"); break;
            case 14: Console.Write("Fourteen"); break;
            case 15: Console.Write("Fifteen"); break;
            case 16: Console.Write("Sixteen"); break;
            case 17: Console.Write("Seventeen"); break;
            case 18: Console.Write("Eighteen"); break;
            case 19: Console.Write("Nineteen"); break;
        }
        if (tensAndOnes > 20)
        {
            switch (ones)
            {
                case 1: Console.Write("-one"); break;
                case 2: Console.Write("-two"); break;
                case 3: Console.Write("-three"); break;
                case 4: Console.Write("-four"); break;
                case 5: Console.Write("-five"); break;
                case 6: Console.Write("-six"); break;
                case 7: Console.Write("-seven"); break;
                case 8: Console.Write("-eight"); break;
                case 9: Console.Write("-nine"); break;
            }
        }
       if (number == 0) Console.Write("Zero");
        Console.ReadKey();
    }
}

하지만 1100을 입력하려고하면 1 천 1 백 대신 1 천 2 백이 출력됩니다.

중첩 된 switch 문을 사용해야하므로 메서드 나 배열을 사용할 수 없습니다.
