Xaml使用style定义trigger进行Foreground颜色渐变

在style中定义ColorAnimation

            <Style x:Key="MyTextBlockStyle" TargetType="{x:Type TextBlock}">
                <Setter Property="TextWrapping" Value="NoWrap" />
                <Setter Property="TextTrimming" Value="None" />

                <Setter Property="FontSize" Value="16" />
                <Setter Property="Foreground" Value="Orange" />
                <Setter Property="FontFamily" Value="SongT" />
                <Style.Triggers>

                    <EventTrigger RoutedEvent="TextBlock.MouseEnter">
                        <BeginStoryboard>
                            <Storyboard Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)">
                                <ColorAnimation From="Orange" To="DodgerBlue" Duration="0:0:0.1"></ColorAnimation>
                            </Storyboard>
                        </BeginStoryboard>

                    </EventTrigger>

                    <EventTrigger RoutedEvent="TextBlock.MouseLeave">
                        <BeginStoryboard>
                            <Storyboard Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)">
                                <ColorAnimation From="DodgerBlue" To="Orange" Duration="0:0:0.1"></ColorAnimation>
                            </Storyboard>
                        </BeginStoryboard>

                    </EventTrigger>

                </Style.Triggers>
            </Style>
