WPF 鼠标滑过列表渐变效果

今天闲来无事，看到很多web的动画效果，用WPF模仿着也写了个简单的。简单的给listboxItem加了个样式。里面就是一个动画，写的比较粗糙。

<Style x:Key="stye1" TargetType="{x:Type ListBoxItem}">
            <Setter Property="Foreground" Value="Snow" />
            <Setter Property="Background" Value="Transparent" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                        <Border Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}">
                            <ContentPresenter />
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <!--  鼠标悬停  -->
                                <Setter Property="Background" Value="Black" />
                                <!--  value中写你要的颜色的值  -->
                            </Trigger>

                            <EventTrigger RoutedEvent="Mouse.MouseLeave">
                                <BeginStoryboard>
                                    <Storyboard>
                                        <ColorAnimation Duration="0:0:0.4"
                                                        From="#AA000000"
                                                        Storyboard.TargetProperty="(ListBoxItem.Background).(SolidColorBrush.Color)"
                                                        To="Transparent" />
                                    </Storyboard>
                                </BeginStoryboard>
                            </EventTrigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
