如何在wpf中使用stackpanel从Listview中获取值

<Grid>
    <ListView x:Name="myListView">
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
                <GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" />
            </GridView>
        </ListView.View>
    </ListView>
    
    <StackPanel Margin="10" VerticalAlignment="Bottom">
        <TextBlock Text="{Binding SelectedPerson.Name, ElementName=myListView}" />
        <TextBlock Text="{Binding SelectedPerson.Age, ElementName=myListView}" />
    </StackPanel>
</Grid>

public partial class MainWindow : Window
{
    public ObservableCollection<Person> People { get; set; }
    public Person SelectedPerson { get; set; }

    public MainWindow()
    {
        InitializeComponent();

        People = new ObservableCollection<Person>
        {
            new Person { Name = "John", Age = 25 },
            new Person { Name = "Jane", Age = 30 },
            new Person { Name = "Mike", Age = 35 }
        };

        myListView.ItemsSource = People;
        myListView.SelectionChanged += MyListView_SelectionChanged;
    }

    private void MyListView_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        SelectedPerson = myListView.SelectedItem as Person;
    }
}

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}
