可以通过在XAML中为Button添加触发器来实现该效果。以下是一个示例:
```xml
<Button Content="Click Me">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Foreground" Value="Black"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect ShadowDepth="0" BlurRadius="20" Color="Red"/>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
<Button.Triggers>
<EventTrigger RoutedEvent="Click">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0.5" Duration="0:0:0.2"/>
<DoubleAnimation Storyboard.TargetProperty="Opacity" From="0.5" To="1" Duration="0:0:0.2" BeginTime="0:0:0.2"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
```
这个样例中,当鼠标悬浮在Button上时,它将变成红色,并且带有一个红色的阴影特效。当单击按钮时,将会有一个渐变的透明度动画。
