我想在我的菜单项中添加单选按钮。

我已经看到了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有适当的单选按钮，可以在Winforms.

为了确保我不会得到与其他人相同的答案，这里是菜单项的单选按钮应该是什么样子的图片：

在此处输入图像描述

顺便说一句，我使用的是 C#，WPF。

您可以通过更改其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>
