2022 - There is a load game feature but no way of saving a game

Issue

The program contains the code required to load a game, but doesn't contain the code to save a game.

The LoadGame method of the BreakThrough class can be seen below:

        private bool LoadGame(string fileName)
        {
            string LineFromFile;
            string LineFromFile2;
            try
            {
                using (StreamReader MyStream = new StreamReader(fileName))
                {
                    LineFromFile = MyStream.ReadLine();
                    Score = Convert.ToInt32(LineFromFile);
                    LineFromFile = MyStream.ReadLine();
                    LineFromFile2 = MyStream.ReadLine();
                    SetupLock(LineFromFile, LineFromFile2);
                    LineFromFile = MyStream.ReadLine();
                    SetupCardCollectionFromGameFile(LineFromFile, Hand);
                    LineFromFile = MyStream.ReadLine();
                    SetupCardCollectionFromGameFile(LineFromFile, Sequence);
                    LineFromFile = MyStream.ReadLine();
                    SetupCardCollectionFromGameFile(LineFromFile, Discard);
                    LineFromFile = MyStream.ReadLine();
                    SetupCardCollectionFromGameFile(LineFromFile, Deck);
                }
                return true;
            }
            catch
            {
                Console.WriteLine("File not loaded");
                return false;
            }
        }

The easiest way to figure out how to save a file is to use the LoadGame sequence, every MyStream.ReadLine() will read one line of the text file. You therefore need to reverse the process.

What does a save game need to write

1. the score
2. the current lock as a string for the conditions
3. the status of the current lock conditions
4. the Hand card collection as a string include card numbers
5. the Sequence card collection as a string include card numbers
6. the Discard card collection as a string include card numbers
7. the Deck card collection as a string include card numbers

What you need to do

Lock class

• create a method to output the lock conditions as a string
• create a method to output the status of the conditions as a string

CardCollection class

• create a method to output the entire collection
• remember to include each card number
• make sure you check if the card collection is not empty

SaveGame method

Create a save game method which sets up a StreamWriter, you can copy the StreamReader code and change read for write, now instead of using myStream.ReadLine use myStream.WriteLine().

The SaveGame method should:

• write the score
• use your method to write the lock condition
• use your method to write the status of each condition
• use your method to write each card collection in order
