    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('Y', 25);
        alphabet.Add('Z', 26);
    
    }
    
    public static int Position(char letter)
    {
        return alphabet\[letter\];
    }

    So, the location of "a" is at "IndexOutOfRangeException"?

          That did have a point. It was actually quite a funny point.

            yes, we need to add 'a' to 'z' in as well. I'll assign it out to one of my team to fix immediately.

              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);
              }
              

              }

                It was written as a follow up to Converting numbers to the word equivalent. [^] since we were getting a lot of "Roman numbers" homework in QA back then.

                          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);

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

                                Even more bonus points for a pointless lookup table for not being able to actually do a lookup :laugh:

                                  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:

                                      Even more bonus points for a pointless lookup table for not being able to actually do a lookup :laugh:

                                        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);

                                          how about :

                                          public class NumberMap
                                          {

                                          static NumberMap()

                                              number.Add('4', 4);
                                              number.Add('5', 5);
                                              number.Add('6', 6);
                                              number.Add('7', 7);
                                              number.Add('8', 8);

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