2022 - When you start the game it automatically loads a saved game, adapt it to ask which game to load

Issue

When you currently start the game you are prompted "Enter L to load a game from a file, anything else to play a new game:> ". This can be found in the SetupGame method of the BreakThrough class. This is shown below:

private void SetupGame()
        {
            string Choice;
            Console.Write("Enter L to load a game from a file, anything else to play a new game:> ");
            Choice = Console.ReadLine().ToUpper();
            if (Choice == "L")
            {
                if (!LoadGame("game1.txt"))
                {
                    GameOver = true;
                }
            }
            else
            {
                CreateStandardDeck();
                Deck.Shuffle();
                for (int Count = 1; Count <= 5; Count++)
                {
                    MoveCard(Deck, Hand, Deck.GetCardNumberAt(0));
                }
                AddDifficultyCardsToDeck();
                Deck.Shuffle();
                CurrentLock = GetRandomLock();
            }
        }

When you choose to load a game, the program automatically loads "game1.txt". The if statement below is what loads the actual file:

                if (!LoadGame("game1.txt"))
                {
                    GameOver = true;
                }

What you need to do

• Add the code to ask for a file name & read it in from the keyboard
• Test if the file name exists, do this using File.Exists("test.txt") this will return true or false
• Create an if statement to use the File.Exists
• if true, load that file,
• if false, load "game1.txt"
