Custom Menu WPF(XAML)
提问by Steve A.
We have dev in our service, a link between wpf xaml with powershell scripts. Actually, we really not have any hard difficults for every simple controls like textbox, richtextbox, button, etc...
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、富文本框、按钮等每个简单的控件，我们真的没有任何困难......
But right now, we want trying to make a menu like notepad for example(file, edit, etc...). The objective is to have a menu style like that : Black Menu
但是现在，我们想尝试制作一个像记事本这样的菜单（文件、编辑等...）。目标是拥有这样的菜单样式：黑色菜单
I have read many threads here and in other website about styling but nothing working(many code are used with the C# so it's complicated to modify it).
我在这里和其他网站上阅读了许多关于样式的主题，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）。
If I understand right, we need to create a custom style for our menu. For example, here my menu :
如果我理解正确，我们需要为我们的菜单创建自定义样式。例如，这里我的菜单：
<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>
Where I need to put the custom style and how? (Background black, text white, hover light blue, submenu background black without white border)
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）
Thanks for your helps and sorry if I'm not clear in my request. Difficult to explain.
感谢您的帮助，如果我的请求不清楚，请见谅。很难解释。

Try something like this:
尝试这样的事情：

I'm sure it can be optimized, but this can give you the way to go.
