How to underline a TextBlock on a MouseEnter
提问by Martin
In a WPF form, I have the following TextBlock. When I move my mouse over it, I would like to see the text of the TextBlock underlined. How can I do that? I tried with TextBlock.Triggers, but it didn't work.
在 WPF 表单中，我有以下 TextBlock。当我将鼠标移到它上面时，我希望看到带下划线的 TextBlock 的文本。我怎样才能做到这一点？我尝试使用 TextBlock.Triggers，但没有奏效。
Thanks!
谢谢！

Use a style:
使用样式：
<TextBlock Text="Hurrah">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="TextDecorations" Value="Underline" />
</Trigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
(Style shown inline for brevity; extract into a resource if you're planning to reuse it.)
（为简洁起见，样式显示为内联；如果您打算重用它，请提取到资源中。）
