C# Why the referenxe to an instance of an object so not work nside button event handlers

[Fex329]

Hi, I am trying to get the button event below to, deactivate, set its content to the player Symbol and to change current player.
Unfortunatley, seems I cannot point to any of the Objects I created in MainWindow() here is the code
I have
Class called Player that has objects with 3 attributes, Name, Score and Symbol.
I am using a buffere Player object to hold the player playing now and the symbo that needs to be added as a symbol on the button (I am creting a TIcTacToe gme in WPF as practice)

The issues I have are
- The currentPlayer and the currentBoard ojecet I have instantiated "do not exist in the current context)
- The reference to the button created in WPF (TopLeftButton.Content = ....) also do not work same error

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        Player _player1 = new Player("Player 1", "X");
        Player _player2 = new Player("Player 2", "O");
        Player currentPlayer = new Player(_player1);
        currentPlayer = _player1;
        Board _currentBoard = new Board();

    }

    private void TopLeftButton_Click(object sender, RoutedEventArgs e)
    {
        this.IsEnabled = false;
        TopLeftButton.Content = currentPlayer.Symbol;
        currentBoard
    }

Your currentPlayer and _currentBoard are defined as local variables within the MainWindow constructor.

You should define these within the class, like so:

public partial class MainWindow : Window
{
    Player _player1;
    Player _player2;
    Board _currentBoard;
    Player currentPlayer;

    public MainWindow()
    {
        InitializeComponent();
        _player1 = new Player("Player 1", "X");
        _player2 = new Player("Player 2", "O");
        currentPlayer = new Player(_player1);
        currentPlayer = _player1;
        _currentBoard = new Board();
    }

    private void TopLeftButton_Click(object sender, RoutedEventArgs e)
    {
        this.IsEnabled = false;
        TopLeftButton.Content = currentPlayer.Symbol;
        // currentBoard
    }
