故事板完成后如何调用方法？

我写下面的代码：

public void name(object sender, RoutedEventArgs e) { DoubleAnimation myDoubleAnimation = new DoubleAnimation(); myDoubleAnimation.From = 1.0; myDoubleAnimation.To = 0.0; myDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.2)); sb1 = new Storyboard(); sb1.Children.Add(myDoubleAnimation); Storyboard.SetTargetName(myDoubleAnimation, one.Name); Storyboard.SetTargetProperty(myDoubleAnimation, new PropertyPath(Grid.OpacityProperty)); sb1.Begin(this); if (one.Opacity == 0) { Container_one.Children.Remove(one); } } 

但它没有正确的做法。 动画工作正常，但删除错误。 如何将Storyboard-End与对方法的调用结合起来？

很多东西。

由于Storyboard的执行是异步的，您需要添加“Storyboard Completed”事件处理程序：

 story.Completed += new EventHandler(Story_Completed); 

然后将删除代码放入：

 private void Story_Completed(object sender, EventArgs e) { if (one.Opacity == 0) { Container_one.Children.Remove(one); } } 

这将在Storyboard完成时执行。
