如何确定鼠标在WPF Calendar控件中停留的日期？

private void Calendar_MouseEnter(object sender, MouseEventArgs e)
{
    Point mousePos = e.GetPosition(calendar);

    HitTestResult hitTestResult = VisualTreeHelper.HitTest(calendar, mousePos);
    if (hitTestResult.VisualHit is FrameworkElement element && element.Tag is DateTime date)
    {
        // 鼠标停留在日期上
        // 可以在这里处理相关逻辑，比如显示日期信息
        Console.WriteLine("Mouse is over date: " + date.ToString("yyyy-MM-dd"));
    }
}

private void Calendar_MouseLeave(object sender, MouseEventArgs e)
{
    // 鼠标离开控件
    // 可以在这里清除之前存储的日期信息
    Console.WriteLine("Mouse left the calendar.");
}
