如何将单选按钮添加到菜单项？

【中文标题】如何将单选按钮添加到菜单项？【英文标题】：How do You Add Radio Buttons To Menu Items? 【发布时间】：2013-02-05 10:45:48 【问题描述】：我想在我的菜单项中添加单选按钮。
我已经看到一些人们将单选按钮作为菜单项的答案。但我希望我的菜单项具有正确的单选按钮，可以在 Winforms 中轻松完成。
为确保我得到的答案与其他人不同，下面是菜单项单选按钮的外观图片：
顺便说一下，我使用的是 C#，WPF。
【问题讨论】：
你见过这个吗？ ***.com/questions/6253145/… @Neil Mitchell：如果您需要支持其他主题，例如 Luna、Aero、Classic 等，可能需要为每个主题样式创建。每个主题都需要为每个主题携带一个样式。这适合你吗？我的意思是，最好专注于功能和单选按钮，至少为他制作一个通用的样式。然后，如果您需要能够使其适合您的风格。如果我或其他人会给你一个单一样式和单选按钮的解决方案，它会来找你吗？ @AnatoliyNikolaev 这个问题只与样式有关 - 编写功能非常简单。我想要的是一种利用主题中已有内容的方法，而不是编写新的样式元素。可能是 WPF 没有为单选菜单按钮定义样式，或者我只是无法正确获取样式。当然，底层操作系统（不是 WPF）确实定义了单选菜单样式。 【参考方案1】：已编辑的模板

感谢您的信息。 点击菜单几次后，需要点击两次才能选择未选中的菜单项。【参考方案2】：您可以通过更改控件的模板属性来更改控件的外观：
<MenuItem>
<MenuItem.Template>
<ControlTemplate>
<RadioButton>Radio</RadioButton>
</ControlTemplate>
</MenuItem.Template>
</MenuItem>
编辑：使用 RadioButton 作为 MenuItem-Icon，以获得图片中显示的外观：
<MenuItem Header="Hallo">
<MenuItem.Icon>
<RadioButton/>
</MenuItem.Icon>
</MenuItem>
【讨论】：
我曾经编写过您所拥有的代码，但它正在制作一个单选按钮，而不是在菜单项文本的右侧有一个带有圆圈的方形框。能否请您提供一些代码，使相同的单选按钮在正方形中有一个圆圈，如我的图片所示？以上是关于如何将单选按钮添加到菜单项？的主要内容，如果未能解决你的问题，请参考以下文章
