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.
解决方法
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.
