WPF动画制作简单的按钮动画

<StackPanel ButtonBase.Click="Grid_Click">
<Button Content="逐渐变大缩小"/>
<Button Content="鼠标移动特效" />
</StackPanel>

//这事件不做过多的解释有基础的一看就会明白
private void Grid_Click(object sender, RoutedEventArgs e)
{
object obj = e.OriginalSource;
Button butn = null;
if (obj is Button)
butn = obj as Button;
Type type = this.GetType();//获取当前实例
Assembly assembly = type.Assembly;//获取在其中声明的类型
//动态的实例化一个对象
Window win = (Window)assembly.CreateInstance(type.Namespace + "." + butn.Content.ToString());
win.Show(); }
下面进行第一个动画：
xaml界面
<Grid>
<Button Content="点击逐渐增长" Height="" HorizontalAlignment="Left" Margin="29,37,0,0" Name="btnGrow1" VerticalAlignment="Top" Width="" />
<Button Content="点击逐渐归位" Height="" HorizontalAlignment="Left" Margin="86,88,0,0" Name="btnBack" VerticalAlignment="Top" Width="" />
<Button Content="点击增长" Height="" HorizontalAlignment="Left" Margin="98,161,0,0" Name="btnGrow" VerticalAlignment="Top" Width="" />
</Grid>
cs:
public 逐渐变大缩小()
{
InitializeComponent();
//给button注册点击事件
btnGrow1.Click += new RoutedEventHandler(btnGrow1_Click);
btnBack.Click += new RoutedEventHandler(btnBack_Click);
btnGrow.Click += new RoutedEventHandler(btnGrow_Click);
}
//点击增长
void btnGrow_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation widthAnimation = new DoubleAnimation() { By=,Duration=TimeSpan.FromSeconds(0.2) };
btnGrow.BeginAnimation(Button.WidthProperty, widthAnimation);
}
//还原动画
void btnBack_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation widthAmination = new DoubleAnimation();
widthAmination.Duration = TimeSpan.FromSeconds();
DoubleAnimation heightAmimation = new DoubleAnimation();
heightAmimation.Duration = TimeSpan.FromSeconds();
btnGrow1.BeginAnimation(Button.WidthProperty, widthAmination);
btnGrow1.BeginAnimation(Button.HeightProperty, heightAmimation);
}
//逐渐增长事件
void btnGrow1_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation widthAnimation = new DoubleAnimation()
{
To = this.Width - ,
Duration = TimeSpan.FromSeconds()
};
DoubleAnimation heightAnimation = new DoubleAnimation()
{
To=(this.Height-)/,
Duration=TimeSpan.FromSeconds()
};
btnGrow1.BeginAnimation(Button.WidthProperty, widthAnimation);
btnGrow1.BeginAnimation(Button.HeightProperty, heightAnimation);
}
