使用单一样式设置 Hyperlink 和 TextBlock 的样式？
我有两种类型的文本，需要遵循基于枚举的类似着色规则：
public enum Modes
{
A,
B,
C
}
带有 DataTrigger 标记的样式用于着色：
<Style TargetType="SEE BELOW" x:Key="Coloring">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=.}" Value="A">
<Setter Property="Foreground" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=.}" Value="B">
<Setter Property="Foreground" Value="Green" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=.}" Value="C">
<Setter Property="Foreground" Value="Blue" />
</DataTrigger>
</Style.Triggers>
</Style>
一种使用场景是 System.Windows.Documents.Hyperlink 带有嵌套的 System.Windows.Controls.TextBlock：
<Hyperlink><TextBlock/></Hyperlink>
另一个只是一个简单的 TextBlock：
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
当然，我可以对两个 TextBlock 进行样式设置 元素：
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
<Hyperlink><TextBlock Style="{StaticResource Coloring}"/></Hyperlink>
但这无法设置超链接大小写下划线的样式。
如果我尝试跨两种类型设置样式：
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
<Hyperlink Style="{StaticResource Coloring}"><TextBlock/></Hyperlink>
则样式会失败，因为（显然）没有可在样式的 TargetType 属性中使用的共同祖先类型。
由于这最终应该是可配置的，因此目标是拥有一个 XAML 文档来定义这些文本块的颜色映射模式。因此，我不愿意有两种定义相同映射的冗余样式（一种用于超链接，一种用于文本块）。
所以...问题：如何在没有冗余 Style XAML 块的情况下对这两种情况保持一致的样式？
I have two types of text that need to follow similar coloring rules based on an enumeration:
public enum Modes
{
A,
B,
C
}
A Style with DataTrigger markup is used to colorize:
<Style TargetType="SEE BELOW" x:Key="Coloring">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=.}" Value="A">
<Setter Property="Foreground" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=.}" Value="B">
<Setter Property="Foreground" Value="Green" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=.}" Value="C">
<Setter Property="Foreground" Value="Blue" />
</DataTrigger>
</Style.Triggers>
</Style>
One use scenario is a System.Windows.Documents.Hyperlink with a nested System.Windows.Controls.TextBlock:
<Hyperlink><TextBlock/></Hyperlink>
and the other is just a simple TextBlock:
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
I can, of course, style both TextBlock elements:
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
<Hyperlink><TextBlock Style="{StaticResource Coloring}"/></Hyperlink>
but that fails to style the underline of the Hyperlink case.
If I try to style across both types:
<TextBlock Style="{StaticResource Coloring}" Text="yada"/>
<Hyperlink Style="{StaticResource Coloring}"><TextBlock/></Hyperlink>
Then the styling fails, as there is (apparently) no common ancestor type for use in the TargetType attribute of the Style.
Since this is suppposed to ultimately be a configurable thing, the goal is to have an XAML document that defines a mode to color mapping for these text blocks. Thus I am reluctant to have two redundant styles (one for Hyperlink and one for TextBlock) that define the same mapping.
So...the question: How can I consistently style both cases without redundant Style XAML blocks?

您可以通过将超链接绑定到样式本身内来强制超链接与其父 TextBlock 具有相同的前景色，如下所示：
在本示例中，我添加了一个设置器来使默认前景为橙色，仅用于测试目的。
You can force Hyperlinks to have the same foreground colour as their parent TextBlocks by binding them within the style itself, like this:
In this example I've added a setter to make the default foreground Orange, just for testing purposes.
发帖后，我意识到了另一种方法。我强制使用嵌套 TextBlock 场景的超链接。如果我要将超链接包装在 TextBlock 中：
那么我的两个案例都会折叠为 TextBlock 样式。 （结合上面的解决方案）
After posting, I realized another approach. I was forcing the Hyperlink with nested TextBlock scenario. If I were to wrap the the Hyperlink in a TextBlock:
Then both my cases collapse to a TextBlock styling. (In combination with the solution above)
