如何在WPF XAML中将Storyboard.TargetProperty设置为DropShadowEffect或BitmapEffect？
我正在学习C#和XAML，但我不知道如何使用它。另外，如果有人知道可以添加到Storyboard.TargetProperty的属性，请列出它们。
我有这段代码，我从ChatGPT和它的工作，但我需要一个XAML和C#的组合;

using System;
using System.Windows;
using System.Windows.Media;
using System.Windows.Media.Effects;
using System.Windows.Media.Animation;
using System.Windows.Input;

namespace WpfApp3
{
    public partial class MainWindow : Window
    {
        private DropShadowEffect shadowEffect;

        public MainWindow()
        {
            InitializeComponent();

            shadowEffect = new DropShadowEffect
            {
                ShadowDepth = 10,
                Color = Colors.Black,
                Opacity = 0,
                BlurRadius =10,
                Direction = 270
            };

            button.Effect = shadowEffect;

            button.MouseEnter += Button_MouseEnter;
            button.MouseLeave += Button_MouseLeave;
        }

        private void Button_MouseEnter(object sender, MouseEventArgs e)
        {
            AnimateShadowOpacity(0.5);
        }

        private void Button_MouseLeave(object sender, MouseEventArgs e)
        {
            AnimateShadowOpacity(0);
        }

        private void AnimateShadowOpacity(double targetOpacity)
        {
            DoubleAnimation animation = new DoubleAnimation
            {
                To = targetOpacity,
                Duration = TimeSpan.FromMilliseconds(250)
            };

            Storyboard storyboard = new Storyboard();
            storyboard.Children.Add(animation);

            Storyboard.SetTargetProperty(animation, new PropertyPath("(UIElement.Effect).(DropShadowEffect.Opacity)"));
            Storyboard.SetTarget(animation, button);

            storyboard.Begin();
        }
    }
}

这是XAML代码
