c# - WPF动画结束时是否会触发任何事件？

WPF Animation结束时会触发任何事件吗？

void HideDefaultScreenImageTimer_Tick(object sender, EventArgs e)
{
    HideDefaultScreenImageTimer.Stop();

    var doubleAnimation = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(0.45)));
    DefaultScreenImage.BeginAnimation(UIElement.OpacityProperty, doubleAnimation);
    // I need some event when an animation ENDS and within that event I want to remove
    // Image (DefaultScreenImage) from Canvas.
    MainCanvas.Children.Remove(DefaultScreenImage);
}

最佳答案

就在这里。
The Completed Event (MSDN)。

因此，您的代码变为:

void HideDefaultScreenImageTimer_Tick(object sender, EventArgs e)
{
    HideDefaultScreenImageTimer.Stop();

    var doubleAnimation = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(0.45)));
    doubleAnimation.Completed += (sender, eArgs) => MainCanvas.Children.Remove(DefaultScreenImage);

    DefaultScreenImage.BeginAnimation(UIElement.OpacityProperty, doubleAnimation);
}
