如何在WPF中设置单个动画重复之间的时间？

// 创建一个DoubleAnimation对象
DoubleAnimation animation = new DoubleAnimation();
animation.From = 0;
animation.To = 100;
animation.Duration = TimeSpan.FromSeconds(1);

// 创建一个Storyboard对象，并将动画添加到Storyboard中
Storyboard storyboard = new Storyboard();
storyboard.Children.Add(animation);

// 设置动画的重复行为
RepeatBehavior repeatBehavior = new RepeatBehavior(3); // 重复3次
repeatBehavior.Delay = TimeSpan.FromSeconds(2); // 每个重复周期之间的延迟时间为2秒
animation.RepeatBehavior = repeatBehavior;

// 将Storyboard关联到某个元素的动画属性上
Storyboard.SetTarget(animation, myElement);
Storyboard.SetTargetProperty(animation, new PropertyPath("Opacity"));

// 启动动画
storyboard.Begin();
