c# - 如何禁用 WPF 动画

Question

我有这段代码，但不知道如何禁用动画。

有什么线索吗？谢谢!

      #region Blinking Animation
            Storyboard sb = new Storyboard();
            if (IsImageBlinking)
            {
                DoubleAnimation da = new DoubleAnimation();

                da.From = 1.0;
                da.To = 0.0;
                da.RepeatBehavior = RepeatBehavior.Forever;
                da.AutoReverse = true;


                sb.Children.Add(da);
                Storyboard.SetTargetProperty(da, new PropertyPath("(Image.Opacity)"));
                Storyboard.SetTarget(da, image1);
                sb.Begin();
            }
            else // This code doesn't disable the animation :(
            {
//!!!! Here I need to disable the animation.  
                sb.Stop();
                sb.Children.Clear();
            }

            #endregion

如果您对 Begin 和 Stop 使用相同 Storyboard 实例，它就会起作用。将 sb 声明为您的类的成员:

public class MainWindow
{
    private Storyboard sb = new Storyboard();

    ...
}
