如何获取按钮的颜色值或画笔？

Question

我为按钮创建了一个控件模板，用于在按下事件期间更改颜色。

我创建了一个模板为

的按钮

            <Button Content="Sample" Height="100" Background="Blue" Foreground="White" BorderBrush="Orange" Template="{StaticResource NewButtonStyle}"/>

，模板是

<phone:PhoneApplicationPage.Resources>
    <ControlTemplate x:Key="NewButtonStyle" TargetType="Button">
        <Grid Background="Transparent">
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="Normal"/>
                    <VisualState x:Name="MouseOver"/>
                    <VisualState x:Name="Pressed">
                        <Storyboard>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground">
                                <DiscreteObjectKeyFrame KeyTime="0" Value="White"/>
                            </ObjectAnimationUsingKeyFrames>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="PressedHighlightBackground" Storyboard.TargetProperty="Background">
                                <DiscreteObjectKeyFrame KeyTime="0" Value="Red"/>
                            </ObjectAnimationUsingKeyFrames>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="BorderBrush">
                                <DiscreteObjectKeyFrame KeyTime="0" Value="Green"/>
                            </ObjectAnimationUsingKeyFrames>
                        </Storyboard>
                    </VisualState>
                    <VisualState x:Name="Disabled">
                        <Storyboard>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground">
                                <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}" />
                            </ObjectAnimationUsingKeyFrames>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="BorderBrush">
                                <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}" />
                            </ObjectAnimationUsingKeyFrames>

                </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>
            <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0" Background="{TemplateBinding Background}" Margin="{StaticResource PhoneTouchTargetOverhang}" >
                <Border x:Name="PressedHighlightBackground" Background="Transparent">
                    <ContentControl x:Name="ContentContainer" Foreground="{TemplateBinding Foreground}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Padding="{TemplateBinding Padding}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                </Border>

        </Grid>
    </ControlTemplate>
</phone:PhoneApplicationPage.Resources>

我所做的就是在新闻发布会期间，我通过将值设置为某些颜色，将边框颜色和背景颜色更改为其他颜色。

但我需要的是，我不需要将值设置为其他颜色，而是需要在新闻事件期间交换背景和边框的颜色。即背景颜色应分配给边框，类似的边框颜色应分配给背景。

请有人帮助我实现这一目标。
