如何在WPF中同步两个滚动条

<ScrollViewer Name="scrollViewer1" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
    <!-- Your content here -->
</ScrollViewer>

<ScrollViewer Name="scrollViewer2" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
    <!-- Your content here -->
</ScrollViewer>

public MainWindow()
{
    InitializeComponent();
    DataContext = this;
}

public static readonly DependencyProperty ScrollValueProperty =
    DependencyProperty.Register("ScrollValue", typeof(double), typeof(MainWindow),
        new PropertyMetadata(0.0, OnScrollValueChanged));

public double ScrollValue
{
    get { return (double)GetValue(ScrollValueProperty); }
    set { SetValue(ScrollValueProperty, value); }
}

private static void OnScrollValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    MainWindow window = d as MainWindow;
    double newValue = (double)e.NewValue;
    
    window.scrollViewer1.ScrollToVerticalOffset(newValue);
    window.scrollViewer2.ScrollToVerticalOffset(newValue);
}

<ScrollViewer Name="scrollViewer1"
              HorizontalScrollBarVisibility="Auto"
              VerticalScrollBarVisibility="Auto"
              VerticalOffset="{Binding ScrollValue, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
    <!-- Your content here -->
</ScrollViewer>

<ScrollViewer Name="scrollViewer2"
              HorizontalScrollBarVisibility="Auto"
              VerticalScrollBarVisibility="Auto"
              VerticalOffset="{Binding ScrollValue, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
    <!-- Your content here -->
</ScrollViewer>
