推荐答案

最简单的方法是使用VisualStateManager并修改MouseOverState

The simplest way is to use the VisualStateManager and modify the MouseOverState

<VisualStateGroup x:Name="CommonStateGroup">
    <VisualState x:Name="MouseOverState">
        <Storyboard>
            <DoubleAnimation From="10" To="0" Duration="00:00:02" 
                             Storyboard.TargetName="blurEffect" 
                             Storyboard.TargetProperty="Radius">
            </DoubleAnimation>
        </Storyboard>
    </VisualState>
    ...
</VisualStateGroup>

您可以使用Transition分别控制Normal-> MouseOver更改和MouseOver-> Normal更改的动画.

You can use the Transition to control the animation for the Normal -> MouseOver change and the MouseOver -> Normal change independently.

然后在显示图像的控件中具有以下Effect:

Then in the control that displays the image have the following Effect:

    <BlurEffect Radius="10" x:Name="blurEffect"/>
