Question

I am retrieving data from a database and trying to populate a List<>. That is my goal.

I am currently inserting the retrieved data into variables within a method and then trying to add the method to the List<>.

Here is my code:

public void Select()
    {
        var sprite = new Sprite();

        if (Game.player.inBattle)
        {
            //Open a connection
            databaseCon.Open(); //Works

            //Create Command
            var cmd = new MySqlCommand(BattleEngine.query, databaseCon); //Works

            //Create a data reader and Execute the command
            var dataReader = cmd.ExecuteReader(); //Works

            try
            {

                //Read the data and store them in the list
                while (dataReader.Read())
                {
                    //Inserts matching Row's first Column attribute into method variable

                    sprite.id = (dataReader.GetInt32(0));
                    //Inserts matching Row's second Column attribute into method variable

                    sprite.identifier = (dataReader.GetString(1)); 

                    Console.WriteLine(sprite.id + ": " + sprite.identifier); //Works. Variables are loaded with data

                    //Fails. Doesn't load the method into the list
                    Game.sprite.Add(new Sprite()); 
                }
            }
            catch (MySqlException ex)
            {
                Console.WriteLine("Error: {0}", ex);

            }
            finally
            {
                if (dataReader != null)
                {
                    //close Data Reader
                    dataReader.Close();
                }

                if (databaseCon != null)
                {
                    //close Connection
                    databaseCon.Close();
                }
            }
        }
    }

I then have a test Console.WriteLine(Game.sprite[0]); setup after this loops and it displays Namespace.Sprite

There are probably other ways of doing this but ultimately I would like to have the list populated with each record within a new method. By storing it in the List<> I can then pull specific information to be used later.

In theory I want to be able to do this;

Console.WriteLine("{0}", Game.sprite[0].id);

I have seen this done before but I cannot seem to replicate it.

ADDITION:

public class Game
{
    public static Player player;
    public static List<Character> sprite;
    GameScreens mainMenu = new GameScreens();
    GameScreens titleScreen = new GameScreens();

    public Game()
    {
        Console.SetWindowSize(100, 50);
        Console.BufferHeight = 50;
        Console.BufferWidth = 100;

        titleScreen.TitleScreen();

        player = new Player();
        sprite = new List<Character>();
        Player.Initialize(player);

        GameLoop();
    }

    void GameLoop() //Our game loop.
    {
        mainMenu.MainMenu();
    }
}

Try:

Game.sprite.Add(sprite);

Instead of:

Game.sprite.Add(new Sprite());

Your code adds an empty Sprite object – not the one you declared
