WPF 样式继承

WPF中设置Button的前景色为红色，默认做法如下：

<StackPanel>
  <StackPanel.Resources>
    <Style TargetType="Button">
      <Setter Property="Foreground" Value="Red" />
   </Style>
  </StackPanel.Resources>

  <Button Content="I'm a red button" />
</StackPanel> 

如果想继承来自Modern UI 中Button的其他样式，可以采用BasedOn实现：

<StackPanel>
  <StackPanel.Resources>
    <Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
      <Setter Property="Foreground" Value="Red" />
   </Style>
  </StackPanel.Resources>

  <Button Content="I'm a red button" />
</StackPanel>
