    And it gets better... Just noticed the next class on from that one:

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

    static ZeroBasedAlphabetPositionMap()
    {
        alphabet.Add('A', 0);
        alphabet.Add('B', 1);
        alphabet.Add('C', 2);
        alphabet.Add('D', 3);
        alphabet.Add('E', 4);
        alphabet.Add('F', 5);
        alphabet.Add('G', 6);
        alphabet.Add('H', 7);
        alphabet.Add('I', 8);
        alphabet.Add('J', 9);
        alphabet.Add('K', 10);
        alphabet.Add('L', 11);
        alphabet.Add('M', 12);
        alphabet.Add('N', 13);

    }
    
    public static int Position(char letter)
    {
        return alphabet\[letter\];
    }

      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);

        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('2', 2);
              number.Add('3', 3);
              number.Add('4', 4);
              number.Add('5', 5);

            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.
