    Just found this gem hiding in a project I've just inherited. Fortunately it doesn't appear to be used.

    public class AlphabetPositionMap
    {
    private static Dictionary<char, int> alphabet = new Dictionary<char, int>();

    static AlphabetPositionMap()
    {
        alphabet.Add('A', 1);
        alphabet.Add('B', 2);
        alphabet.Add('C', 3);
        alphabet.Add('D', 4);
        alphabet.Add('E', 5);
        alphabet.Add('F', 6);
        alphabet.Add('G', 7);
        alphabet.Add('H', 8);
        alphabet.Add('I', 9);
        alphabet.Add('J', 10);
        alphabet.Add('K', 11);
        alphabet.Add('L', 12);
        alphabet.Add('M', 13);

      How about adding another lookup that gets the uppercase equivalent of a lowercase letter?

        how about :

        public class NumberMap
        {
        private static Dictionary number = new Dictionary();

        static NumberMap()
        {
            number.Add('1', 1);
            number.Add('2', 2);
            number.Add('3', 3);
            number.Add('4', 4);
            number.Add('5', 5);
            number.Add('6', 6);
            number.Add('7', 7);
            number.Add('8', 8);
            number.Add('9', 9);
            number.Add('0', 0);
        }
        

        }

          AlphabetPositionMap seems to have a brother called ZeroBasedAlphabetPositionMap[^]. Yes, it is missing lowercaps variants, meaning there should at least be four of these methods. And globalization is missed completely. Scheiß drauf.

            I thought I had a more useless lookup table, but I was wrong

            private static Dictionary alphabet = new Dictionary();
            static AlphabetPositionMap()
            {
            alphabet['A'] = 'A';
            alphabet['B'] = 'B';
            // you get the idea
            }

            I am wrong because it is only a small step from this code to creating an Enigma machine in software, which I believe had some amount of use a few years back. Failed at being useless :sigh:

                  I've noticed that you do not cover lowercase numbers.

                      I was thinking more of something like "1".tolower might work.
