Question

我想找到一种更简洁的方法来获取动画完成回调，以便在== from时触发。现在我通过向我的价值中添加一小部分来破解这个工作。还有更好的方法吗？

    //todo is there a way to get animations to call their Complete() even when to == from?
    if (to.Equals(from)) {
        from += .01;
    }

    DoubleAnimation animation = new DoubleAnimation {
        Name = axis == Axis.X ? TranslateTransform.XProperty.Name : TranslateTransform.YProperty.Name,
        From = from,
        To = to,
        Duration = TimeSpan.FromSeconds(translate.Time),
        FillBehavior = FillBehavior.Stop,
        EasingFunction = translate.Curve.ToEase(),
        IsAdditive = false,

    };

    AnimationClock = animation.CreateClock();

    AnimationClock.Completed += (sender, args) => {

    };

您可以在创建动画之前检查值如果持续时间很重要，您可以启动计时器并在计时器启动时启动。

这样的事情可以解决问题：

if (to.Equals(from)) {
        if (_timer == null)
        {
            _timer = new Timer(x =>
            {
                //completeCode
            }, null, translate.Time * 1000, Timeout.Infinite);
        }
        else
        {
            _timer.Change(translate.Time * 1000, Timeout.Infinite);
        }
    return;       
}

WPF动画：如果要==来自，则不会调用完整的回调
