c# - 动画 DropShadowEffect 颜色

Question

如何在不需要重新应用新元素的情况下为DropShadowEffect's已经应用到元素的颜色设置动画？XAMLDropShadowEffect

我试过这个：

    private void test()
    {
        DropShadowEffect DS_Moon = (DropShadowEffect)Application.Current.Resources["DS_Moon"];

        ColorAnimation DS_Moonlight = new ColorAnimation();
        DS_Moonlight.From = new Color()
        {
            A = (byte)1,
            R = (byte)0,
            G = (byte)0,
            B = (byte)0
        };
        DS_Moonlight.To = new Color()
        {
            A = (byte)1,
            R = (byte)255,
            G = (byte)255,
            B = (byte)255
        };

        DS_Moon.BeginAnimation(SolidColorBrush.ColorProperty, (AnimationTimeline)DS_Moonlight);
    }

但DS_Moon回报Null！

我刚刚意识到我可以做到这一点：

Moon.Effect.BeginAnimation(DropShadowEffect.ColorProperty, (AnimationTimeline)DS_Moonlight);
