Example animation of storyboard in WP7

If you want to implement such a control, its transparency will be smoothly transitioned from 0 to 1, and then smoothly transitioned from 1 to 0 (that is, the flickering effect in the dark ).

One way is to define a timer and repeatedly change its transparency.

One way is to use storyboard to achieve this flickering effect. The code is more concise and the code is as follows:

        private Storyboard PrepareShowStory()        {            Storyboard story = new Storyboard();            DoubleAnimation animation;            animation = new DoubleAnimation();            animation.From = 0;            animation.To = 1;            animation.Duration = new Duration(TimeSpan.FromMilliseconds(Duration));            Storyboard.SetTarget(animation, MyTestImage);            Storyboard.SetTargetProperty(animation, new PropertyPath("(UIElement.Opacity)"));            story.Children.Add(animation);            story.AutoReverse = true;            story.RepeatBehavior = RepeatBehavior.Forever;            return story;        }

To start the animation, you can set it as follows:

m_StoryBoard = PrepareShowStory();m_StoryBoard.Begin();

To pause an animation, you can:

m_StoryBoard.Pause();

To re-run the animation, you can:

m_StoryBoard.Resume();

To end the animation, you can:

m_StoryBoard.Stop();
