c# - 故事板 c# 动画

Question

好吧，我希望房子图像从 to 旋转-5°，5°我写了以下代码

        Duration duration2 = new Duration(TimeSpan.FromSeconds(1));

        Storyboard sb2 = new Storyboard();
        sb2.Duration = duration2;

        DoubleAnimation da2 = new DoubleAnimation();
        da2.Duration = duration2;

        sb2.Children.Add(da2);

        RotateTransform rt2 = new RotateTransform();

        Storyboard.SetTarget(da2, rt2);
        Storyboard.SetTargetProperty(da2, new PropertyPath("Angle"));
        da2.From = 5;
        da2.To = -5;

        HouseImg.RenderTransform = rt2;
        HouseImg.RenderTransformOrigin = new Point(0.5, 0.5);

        sb2.RepeatBehavior = RepeatBehavior.Forever;
        sb2.Begin();

但是当它结束时它会迅速进入开始（5°），我想要的也是动画。所以总结一下：我想动画从5°到-5°和从-5°到5°也。

Tnx :)

将AutoReverse属性设置为true。

sb2.AutoReverse = true;
