如何在UWP中实现InkCanvas和Canvas之间的切换

<Grid>
    <InkCanvas x:Name="inkCanvas" />
    <Canvas x:Name="canvas" Visibility="Collapsed" />
</Grid>

private void SwitchButton_Click(object sender, RoutedEventArgs e)
{
    if (inkCanvas.Visibility == Visibility.Visible)
    {
        // 切换到Canvas
        inkCanvas.Visibility = Visibility.Collapsed;
        canvas.Visibility = Visibility.Visible;
    }
    else
    {
        // 切换到InkCanvas
        canvas.Visibility = Visibility.Collapsed;
        inkCanvas.Visibility = Visibility.Visible;
    }
}

private void SwitchButton_Click(object sender, RoutedEventArgs e)
{
    if (inkCanvas.Visibility == Visibility.Visible)
    {
        // 保存InkCanvas的绘图数据
        var inkData = inkCanvas.InkPresenter.StrokeContainer.GetStrokes();
        // 切换到Canvas
        inkCanvas.Visibility = Visibility.Collapsed;
        canvas.Visibility = Visibility.Visible;
        // 在Canvas中加载绘图数据
        foreach (var stroke in inkData)
        {
            // 将stroke添加到canvas中
            canvas.Children.Add(stroke);
        }
    }
    else
    {
        // 在Canvas中保存绘图数据
        var inkData = new List<InkStroke>();
        foreach (var child in canvas.Children)
        {
            if (child is InkStroke stroke)
            {
                inkData.Add(stroke);
            }
        }
        // 清空Canvas
        canvas.Children.Clear();
        // 切换到InkCanvas
        canvas.Visibility = Visibility.Collapsed;
        inkCanvas.Visibility = Visibility.Visible;
        // 在InkCanvas中加载绘图数据
        inkCanvas.InkPresenter.StrokeContainer.AddStrokes(inkData);
    }
}
