在WPF中创建菜单时，将显示左对齐的菜单项框。 是否有任何属性使其显示为右侧对齐？（如windows窗体）

我一直在互联网上搜索，但没有成功，非常感谢您提供的任何帮助

/*XAML代码*/

   <Menu>
        <MenuItem Header="One">
            <MenuItem Header="One-One"></MenuItem>
            <MenuItem Header="One-Two"></MenuItem>
            <MenuItem Header="One-Three"></MenuItem>
            <MenuItem Header="One-Four"></MenuItem>
            <MenuItem Header="One-Five"></MenuItem>
        </MenuItem>
        <MenuItem Header="Two">
            <MenuItem Header="Two-One"></MenuItem>
            <MenuItem Header="Two-Two"></MenuItem>
            <MenuItem Header="Two-Three"></MenuItem>
            <MenuItem Header="Two-Four"></MenuItem>
            <MenuItem Header="Two-Five"></MenuItem>
        </MenuItem>

    </Menu>

您可以像这样编辑菜单项的模板

对我有效的方法如下：

    <Menu>
    <MenuItem Header="_One">
        <MenuItem Header="_One-One"></MenuItem>
        <MenuItem Header="_One-Two"></MenuItem>
        <MenuItem Header="_One-Three"></MenuItem>
        <MenuItem Header="_One-Four"></MenuItem>
        <MenuItem Header="_One-Five"></MenuItem>
    </MenuItem>
    <MenuItem Header="_Two">
        <MenuItem Header="_Two-One"></MenuItem>
        <MenuItem Header="_Two-Two"></MenuItem>
        <MenuItem Header="_Two-Three"></MenuItem>
        <MenuItem Header="_Two-Four"></MenuItem>
        <MenuItem Header="_Two-Five"></MenuItem>
    </MenuItem>

</Menu>
在名称前放置一个u，使其成为热键CTRL+标题名称，但我的名称也很好地对齐。

问题出在注册表编辑器上

此网页解决了我的问题：

在我的情况下，只需删除HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows中的键“MenuDropAlignment”或将其设置为0即可解决问题

希望这个答案能帮助其他有同样问题的人

感谢那些试图帮忙的人。

多亏了那些尽力帮忙的人。

是的，这几乎肯定是重复的。答案的要点是，对齐与您的应用程序无关。它基于Windows中的“左手或右手”设置，使菜单更易于触摸使用。是的，这几乎肯定是重复的。答案的要点是，对齐与您的应用程序无关。它基于Windows中的“左手或右手”设置，使菜单更易于触摸使用。不幸的是，它不起作用：（它使菜单框看起来更好（更薄），但行为仍然相同。感谢老兄，这是最好的答案不幸的是，它不起作用：（它使菜单框看起来更好（更薄）但是行为还是一样。谢谢老兄，这是最好的回答。它不起作用，我的朋友。谢谢你的帮助！它不起作用，我的朋友。谢谢你的帮助！
