wpf - 为什么我不能在动画后修改对象？

Question

执行这段代码后...

DoubleAnimation a = new DoubleAnimation(newWidth, new Duration(...));
ThicknessAnimation b = new ThicknessAnimation(new Thickness(...), new Duration(...));
border.BeginAnimation(Border.MarginProperty, b);
border.BeginAnimation(Border.WidthProperty, a);

...此代码不再有效(分配新值后边距不会更改):

// doesn't have any effect
border.Margin = new Thickness(...);

这是怎么回事？？谢谢!

来自 Dependency Properties Overview :

Dependency properties can be animated. When an animation is applied and is running, the animated value operates at a higher precedence than any value (such as a local value) that the property otherwise has.

您需要将动画的 FillBehavior 设置为 Stop 以使本地值优先。
