场景：样式Ａ和样式Ｂ的背景颜色一样，但是文字颜色不一样

<Style x:key="BaseStyle" TargetType="Button">
    <Setter Property="Background" Value="White">
</Style>

<Style x:key="RedStyle"  BaseOn="{StaticResource BaseStyle}" TargetType="Button">
    <Setter Property="Foreground" Value="Red" />
</Style>

<Style x:key="BludStyle" BaseOn="{StaticResource BaseStyle}" TargetType="Button">
    <Setter Property="Foreground" Value="Blue" />
</Style>

<!-- 如果不指定Target，设置Property时需要使用Control. -->
<Style x:key="BaseTyle">
    <Setter Property="Control.Background" value="Black" />
</Style>
<Style x:key="RedStyle"  BaseOn="{StaticResource BaseStyle}" TargetType="Button">
    <Setter Property="Foreground" Value="Red" />
</Style>

<Style x:key="BludStyle" BaseOn="{StaticResource BaseStyle}" TargetType="TextBox">
    <Setter Property="Foreground" Value="Blue" />

<!-- 继承基础样式 -->
<Style TargetType="TextBlock" BasedOn="{StaticResource {x:Type TextBlock}}">
