线条样式的TargetType在UWP中不起作用

在UWP中，TargetType属性用于指定样式应用的目标类型。然而，对于线条样式（StrokeStyle）来说，TargetType属性在UWP中不起作用。线条样式是指在绘制图形或路径时，定义线条的样式，如线宽、线段样式等。

在UWP中，要应用线条样式，可以通过以下步骤实现：

创建一个自定义控件或使用现有的控件。
在控件的样式中，使用Setter元素设置控件的Stroke属性为所需的线条样式。
在控件的样式中，使用Setter元素设置控件的StrokeThickness属性为所需的线条宽度。

例如，以下是一个自定义Button控件的样式，应用了一种虚线样式的线条：

<Style TargetType="Button">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
    <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}"/>
    <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}"/>
    <Setter Property="Padding" Value="8,4,8,4"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
    <Setter Property="FontWeight" Value="Normal"/>
    <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
    <Setter Property="UseSystemFocusVisuals" Value="True"/>
    <Setter Property="FocusVisualMargin" Value="-3"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="PointerOver">

                                                                   Storyboard.TargetProperty="Foreground">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlHighlightBaseHighBrush}"/>

            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

在上述样式中，我们通过设置Button控件的BorderBrush属性为所需的线条样式，实现了线条样式的应用。

对于线条样式的应用场景，可以用于绘制图形、路径、边框等需要自定义线条样式的界面元素。
