Wpf 只需更改按钮的背景图像几秒钟

我有一个使用按钮的WPF应用程序（惊喜）

我对它进行了样式设计，这样当用户单击按钮时，背景图像将变为红色

我想发生的是，几秒钟后，背景恢复到原来的背景

我不知道该怎么做

这是我目前的代码：

<Style x:Key="RoundButtonTemplate" TargetType="Button">
    <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">                       
                    <Border CornerRadius="5" Background="{TemplateBinding Background}"
                            BorderThickness="1">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center">
                        </ContentPresenter>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsFocused" Value="true">
                            <Setter Property="Background">
                                <Setter.Value>
                                    <ImageBrush ImageSource="{StaticResource RedButtonBackGround}"/>
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Width" Value="74"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Height" Value="27"></Setter>
        <Setter Property="Background">
            <Setter.Value>
                <ImageBrush ImageSource="{StaticResource ButtonBackGround}"/>
            </Setter.Value>
        </Setter>
    </Style>

以下是一个解决方案，用于基于双动画，使用关键帧和不透明度设置背景图像动画

更新-2按钮样式代码（放入您的资源部分）

第一个DoubleAnimationUsingKeyFrames部分将矩形VisibleOncklick的不透明度从1更改为0。2秒后

第二个DoubleAnimationUsingKeyFrames部分将MyBorder的不透明度从0更改为1。2秒后

要使动画速度更快，请使用关键帧更改两个DoubleAnimationUsingKeyFrames部分的关键帧时间参数：

选项

                                       <DoubleAnimationUsingKeyFrames Storyboard.TargetName="RectangleVisibleOnCklick" 
                                   Storyboard.TargetProperty="(FrameworkElement.Opacity)">
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.25" Value="1" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0.5" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.75" Value="0.25" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:1" Value="0.0" />
                                    </DoubleAnimationUsingKeyFrames>
                                    <DoubleAnimationUsingKeyFrames Storyboard.TargetName="MyBorder" 
                                   Storyboard.TargetProperty="(FrameworkElement.Opacity)">
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.25" Value="0" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0.25" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:0.75" Value="0.5" />
                                        <EasingDoubleKeyFrame KeyTime="0:0:1" Value="1.0" />
                                    </DoubleAnimationUsingKeyFrames>

                                        <EasingDoubleKeyFrame KeyTime="0:0:1" Value="0.0" />
                                    </DoubleAnimationUsingKeyFrames>
                                    <DoubleAnimationUsingKeyFrames Storyboard.TargetName="MyBorder"

带有椭圆形内容的矩形按钮（由于使用关键帧动画，单击时为椭圆形）

问候。
