WPF 中的动画主要分为 AnimationTimeline（简单动画） 和 Storyboard（一组协同的动画）。
<Button Height="80" Width="200" Content="Move" Click="ButtonBase_OnClick">
<Button.RenderTransform>
<TranslateTransform x:Name="tt" X="0" Y="0"></TranslateTransform>
</Button.RenderTransform>
</Button>
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
DoubleAnimation dx = new DoubleAnimation();
DoubleAnimation dy = new DoubleAnimation();
// 指定起点
dx.From = 0;
dy.From = 0;
// 指定终点
dx.To = new Random().NextDouble() * 200;
dy.To = new Random().NextDouble() * 200;
//// 指定幅度
//dx.By = 100;
//dy.By = 100;
// 指定时长
dx.Duration = new Duration(TimeSpan.FromMilliseconds(1000));
dy.Duration = new Duration(TimeSpan.FromMilliseconds(2000));
// 动画主体（TranslateTransform）
tt.BeginAnimation(TranslateTransform.XProperty,dx);
tt.BeginAnimation(TranslateTransform.YProperty,dy);
}
<!--弹跳移动-->
<Button Margin="0,0,600,350" Content="弹跳" Click="ButtonBase_OnClick1">
<Button.RenderTransform>
<TranslateTransform x:Name="tt1" X="0" Y="0"></TranslateTransform>
</Button.RenderTransform>
</Button>
private void ButtonBase_OnClick1(object sender, RoutedEventArgs e)
{
DoubleAnimation dx=new DoubleAnimation();
DoubleAnimation dy=new DoubleAnimation();
// 设置弹跳
BounceEase be=new BounceEase()
{
Bounces = 4, // 弹跳次数
Bounciness = 2,// 弹跳值
};
dy.EasingFunction = be;
// 设置终点
dx.To = 300;
dy.To = 300;
// 设置时长
dx.Duration = new Duration(TimeSpan.FromMilliseconds(2000));
dy.Duration = new Duration(TimeSpan.FromMilliseconds(2000));
// 动画主体
tt1.BeginAnimation(TranslateTransform.XProperty,dx);
tt1.BeginAnimation(TranslateTransform.YProperty, dy);
}
<!--路径-->
<PathGeometry x:Key="MovePath" Figures="M0,150 C300,-100 300,400 600,120"></PathGeometry>
<!--路径移动-->
<Button Margin="0,100,600,250" Content="路径移动" Click="ButtonBase_OnClick2">
<Button.RenderTransform>
<TranslateTransform x:Name="tt2" X="0" Y="0"></TranslateTransform>
</Button.RenderTransform>
</Button>
private void ButtonBase_OnClick2(object sender, RoutedEventArgs e)
{
PathGeometry path=this.FindResource("MovePath") as PathGeometry;
Duration duration =new Duration(TimeSpan.FromMilliseconds(3000));
// 创建动画
DoubleAnimationUsingPath dx=new DoubleAnimationUsingPath()
{
PathGeometry = path,
Source = PathAnimationSource.X,
Duration = duration,
};
DoubleAnimationUsingPath dy = new DoubleAnimationUsingPath()
{
PathGeometry = path,
Source = PathAnimationSource.Y,
Duration = duration,
};
// 执行动画
tt2.BeginAnimation(TranslateTransform.XProperty,dx);
tt2.BeginAnimation(TranslateTransform.YProperty, dy);
}
例如：实现三个小球（红球、绿球、蓝球）分别沿着跑到运动的动画，具体示例如下：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="100"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Border Grid.Row="0" Grid.Column="0" BorderThickness="2" BorderBrush="Red">
<Ellipse x:Name="RedEllipse" Width="36" Height="36" VerticalAlignment="Bottom" HorizontalAlignment="Left" Fill="Red">
<Ellipse.RenderTransform>
<TranslateTransform x:Name="RedTransform"></TranslateTransform>
</Ellipse.RenderTransform>
</Ellipse>
</Border>
<Border Grid.Row="1" Grid.Column="0" BorderThickness="2" BorderBrush="Green">
<Ellipse x:Name="GreenEllipse" Width="36" Height="36" VerticalAlignment="Bottom" HorizontalAlignment="Left" Fill="Green">
<Ellipse.RenderTransform>
<TranslateTransform x:Name="GreenTransform"></TranslateTransform>
</Ellipse.RenderTransform>
</Ellipse>
</Border>
<Border Grid.Row="2" Grid.Column="0" BorderThickness="2" BorderBrush="Blue">
<Ellipse x:Name="BlueEllipse" Width="36" Height="36" VerticalAlignment="Bottom" HorizontalAlignment="Left" Fill="Blue">
<Ellipse.RenderTransform>
<TranslateTransform x:Name="BlueTransform"></TranslateTransform>
</Ellipse.RenderTransform>
</Ellipse>
</Border>
<Button Grid.Row="0" Grid.Column="1" Grid.RowSpan="3" Content="GO!">
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="RedTransform"
Storyboard.TargetProperty="X"
To="650"
Duration="0:1:0"
></DoubleAnimation>
<DoubleAnimation Storyboard.TargetName="GreenTransform"
Storyboard.TargetProperty="X"
To="650"
Duration="0:0:0.8"
></DoubleAnimation>
<DoubleAnimation Storyboard.TargetName="BlueTransform"
Storyboard.TargetProperty="X"
To="650"
Duration="0:0:10"
></DoubleAnimation>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
</Grid>
