Accessing a MainWindow list from another window (Protection)

I have this code over here from MainWindow.xaml.cs in a WPF application

public partial class MainWindow : Window
{

    animaciones.Preferences Preferences;
    animaciones.GameOver GameOver;
    ObservableCollection<Figura> listafiguras = new ObservableCollection<Figura>();
    System.Media.SoundPlayer player = new System.Media.SoundPlayer();
    DispatcherTimer timer;
    Raton raton;

    public MainWindow()
    {
        InitializeComponent();
        Preferences = new animaciones.Preferences();
        GameOver = new animaciones.GameOver();
        raton = new Raton();
        player.SoundLocation = "lostwoods.wav";
        Canvas.SetLeft(raton.fig, raton.x);
        Canvas.SetBottom(raton.fig, raton.y);
        lienzo.Children.Add(raton.fig);

        this.KeyDown += new KeyEventHandler(KeyDownEventos);

        timer = new DispatcherTimer();
        timer.Tick += OnTick;
        timer.Interval = new TimeSpan(0, 0, 0, 0, 50);


    }

I want to use the "listafiguras" ObservableCollection in another xaml.cs like this:

 public partial class Preferences : Window
{


    public Preferences()
    {
        InitializeComponent();
        tabla.ItemsSource = MainWindow.listafiguras;
    }

But it says MainWindow is not accesible due its protection level. How can I change that to give access to my variable? Thank you

listafiguras is private to your MainWindow class and thus not accessible to anything outside of Mainwindow. You can perhaps pass this list as a constructor parameter to Preferences :

public Preferences(ObservableCollection<Figura> figuraList)
    {
        InitializeComponent();
        tabla.ItemsSource = figuraList;
    }

In MainWindow:

Preferences = new animaciones.Preferences(listafiguras );

However i suggest you look into using services and DI frameworks for sharing data between views for a more general solution to this type of problem (see What exactly are "WPF services"?)
