      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);

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

            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:

                      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);
                          alphabet.Add('N', 14);
                          alphabet.Add('O', 15);
                          alphabet.Add('P', 16);
                          alphabet.Add('Q', 17);
                          alphabet.Add('R', 18);
                          alphabet.Add('S', 19);
                          alphabet.Add('T', 20);
                          alphabet.Add('U', 21);
                          alphabet.Add('V', 22);
                          alphabet.Add('W', 23);
                          alphabet.Add('X', 24);
                          alphabet.Add('Y', 25);
                          alphabet.Add('Z', 26);
                      
                      }
                      
                      public static int Position(char letter)
                      {
                          return alphabet\[letter\];
                      }
                      

                      }

                        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);
                        }
                        

                        }

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

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