自定义菜单 WPF(XAML)

Question

我们的服务中有 dev，wpf xaml 与 powershell 脚本之间的链接。 实际上，对于文本框、richtextbox、按钮等每一个简单的控件，我们真的没有任何难度......

但现在，我们想尝试制作一个类似记事本的菜单（文件、编辑等...）。目标是拥有这样的菜单样式：Black Menu

我在这里和其他网站上阅读了很多关于样式的线程，但没有任何效果（许多代码与 C# 一起使用，因此修改它很复杂）。

如果我理解正确，我们需要为菜单创建自定义样式。例如，这里是我的菜单：

<Window x:Class="Test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:eo="http://schemas.essentialobjects.com/wpf/"
        Title="MainWindow" Height="250" Width="350">
    <StackPanel>
        <Menu>
            <MenuItem Header="_File">
                <MenuItem Header="_New" />
                <MenuItem Header="_Save" />
                <MenuItem Header="_Quit" />
            </MenuItem>
            <MenuItem Header="_Edit">
                <MenuItem Header="_Copy" />
                <MenuItem Header="_Cut" />
                <MenuItem Header="_Paste" />
            </MenuItem>
        </Menu>
    </StackPanel>
</Window>

我需要在哪里放置自定义样式以及如何放置？ （背景黑色，文字白色，悬停浅蓝色，子菜单背景黑色无白边框）

感谢您的帮助，如果我的请求不清楚，我们深表歉意。很难解释。

试试这样的：
