如果有任何方法可以使按钮悬停并单击图像更改，您能帮我吗？这是我当前的代码：

<Window.Background>
    <ImageBrush ImageSource="pack://siteoforigin:,,,/MOP Launcher BG.png"/>
</Window.Background>
<Grid>
    <Button x:Name="playbtn" Content="Button" HorizontalAlignment="Left" Height="91" Margin="779,422,0,0" VerticalAlignment="Top" Width="165" Foreground="{x:Null}" BorderBrush="{x:Null}" Template="{DynamicResource ButtonControlTemplate2}" >
        <Button.Background>
            <ImageBrush ImageSource="play.png"/>

        </Button.Background>

    </Button>
</Grid>

您可以使用按钮样式更改图像刷，如下所示：

      <Button>
            <Button.Style>
                <Style TargetType="Button">
                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter Property="Background">
                                <Setter.Value>
                                    <ImageBrush ImageSource="play.png"/>
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                        <Trigger Property="IsMouseCaptureWithin" Value="true">
                            <Setter Property="Background">
                                <Setter.Value>
                                    <ImageBrush ImageSource="pause.png"/>
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </Button.Style>
        </Button>

谢谢
