WPF实现左右移动（晃动）动画效果_实用技巧_

 private void Button_Click(object sender, RoutedEventArgs e) { DoubleAnimation DAnimation = new DoubleAnimation(); DAnimation.From = 100;//起点 DAnimation.To = 280;//终点 DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间 Storyboard.SetTarget(DAnimation, GroupboxArea); Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty)); Storyboard story = new Storyboard(); story.Completed += new EventHandler(story_Completed);//完成后要做的事 //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上 story.Children.Add(DAnimation); story.Begin(); } void story_Completed(object sender, EventArgs e) { DoubleAnimation DAnimation = new DoubleAnimation(); DAnimation.From = 280;//起点 DAnimation.To = 100;//终点 DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间 Storyboard.SetTarget(DAnimation, GroupboxArea); Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty)); Storyboard story = new Storyboard(); story.Completed += new EventHandler(storyCompleted);//完成后要做的事 //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上 story.Children.Add(DAnimation); story.Begin(); } void storyCompleted(object sender, EventArgs e) { DoubleAnimation DAnimation = new DoubleAnimation(); DAnimation.From = 100;//起点 DAnimation.To = 200;//终点 DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间 Storyboard.SetTarget(DAnimation, GroupboxArea); Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty)); Storyboard story = new Storyboard(); //story.Completed += new EventHandler(storyCompleted);//完成后要做的事 //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上 story.Children.Add(DAnimation); story.Begin(); }
