        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);

              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.
