C#动画：
两点动画，旋转动画，变色动画
1.边框
border：可以容纳一个其他元素
BorderThickness：边框厚度
BorderBrush：边框颜色
CornerRadius：设置边框圆角
添加动画的几大步骤：
1.设置边框border
using System.Windows.Media.Animation;添加动画前必须先命名动画空间
Storyboard story1 = new Storyboard();
4，选择动画类型：DoubleAnimation 动画名称= new DoubleAnimation();
5，设置动画的属性（5个必选属性，2个可选属性）：①----⑤必选属性 ⑥ ⑦可选属性
①From:设置动画的起始值
②to:设置动画的终止值
③Duration:设置动画的进行时间
④Storyboard.SetTarget:设置某个动画的主角(设置的动画，要作为目标的依赖对象)
⑤ Storyboard.SetTargetProperty:设置动画的属性
⑥ AutoReverse:设置动画可逆播放
⑦RepeatBehavior:是否重复播放
6,.将动画添加进故事本中:story1.children.Add(动画名);
7.开启动画：动画名称.Begin();

//动画：
//1.添加故事本
Storyboard story1 = new Storyboard();
//2.选择动画类型：两点动画
DoubleAnimation anim = new DoubleAnimation();
//3.设置动画起始值
anim.From =100;
//3.设置动画终止值
anim.To = 200;
//4.设置动画进行时间
anim.Duration = new Duration(TimeSpan.FromSeconds(2));
//5.设置动画主角
Storyboard.SetTarget(anim, bd);
//6.设置动画属性：

案例2.动画类型：旋转动画
设置旋转的方向 RotateTransform rotate = new RotateTransform();
给对象设置，绑定旋转中心 br.RenderTransform = rotate;

br.Width = 200;
br.Height = 210;
br.Background = Brushes.LightBlue;
Canvas.SetLeft(br, 150);
Canvas.SetTop(br, 150);
BG.Children.Add(br);
//设置旋转方向
RotateTransform rotate = new RotateTransform();
//绑定旋转中心
br.RenderTransform = rotate;
//设置旋转中心百分比
br.RenderTransformOrigin = new Point(0.5, 0.5);
Storyboard story = new Storyboard();
DoubleAnimation da = new DoubleAnimation(0, 360, new Duration(TimeSpan.FromSeconds(3)));
Storyboard.SetTarget(da, br);
Storyboard.SetTargetProperty(da, new PropertyPath("RenderTransform.Angle"));
story.Children.Add(da);
story.Begin();
}
}
}

Opacity = 1;
//改变背景颜色
Storyboard story = new Storyboard();
ColorAnimation coloran = new ColorAnimation(Colors.SkyBlue, Colors.Plum, new Duration(TimeSpan.FromSeconds(6)));
Storyboard.SetTarget(coloran, br);
Storyboard.SetTargetProperty(coloran, new PropertyPath("(Border.Background).(SolidColorBrush.Color)"));

//Storyboard story = new Storyboard();
ColorAnimation colorbr = new ColorAnimation(Colors.YellowGreen, Colors.Yellow, new Duration(TimeSpan.FromSeconds(6)));
Storyboard.SetTarget(colorbr, br);
Storyboard.SetTargetProperty(colorbr, new PropertyPath("(Border.BorderBrush).(SolidColorBrush.Color)"));

story.Begin();
//改变边框厚度，
ThicknessAnimation ta = new ThicknessAnimation(new Thickness(20),new Thickness(0),new Duration(TimeSpan.FromSeconds(6)));
Storyboard.SetTarget(ta, br);
Storyboard.SetTargetProperty(ta, new PropertyPath("BorderThickness"));
DoubleAnimation da = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(5)));
Storyboard.SetTarget(da, br);
//改变边框透明度
Storyboard.SetTargetProperty(da, new PropertyPath("Opacity"));
story.Children.Add(da);
story.Begin();
}
}
