c# - How do I add the item I selected in the Combobox to the list box on another page in WPF

Question

**Combobox XAML**

Items in the ComboBox come from an array. Therefore it does not appear in XAML

    <ComboBox Name="cbSelectMovie" HorizontalAlignment="Left" Margin="252,174,0,0" VerticalAlignment="Top" Width="196" Height="32" SelectionChanged="cbSelectMovie_SelectionChanged">

When the button is pressed, it is added to the ListBox.

<Button Content="Ad Movie..." HorizontalAlignment="Left" FontSize="14" Margin="56,264,0,0" VerticalAlignment="Top" Width="165" Height="46" Click="Button_Click" />

ListBox on another page

 <ListBox x:Name="movieListBox" HorizontalAlignment="Left" Height="326" Margin="38,44,0,0" VerticalAlignment="Top" Width="231"/>

I did such a try, but unfortunately, it didn't work.

 private void Button_Click(object sender, RoutedEventArgs e)
    {
        string x = " " ;
        MovieList mv = new MovieList();
        // mv.MovieListBox = cbSelectMovie.Text;
        cbSelectMovie.SelectedItem = x.ToString();
        mv.MovieListBox.Items.Add(x);

    }
