六、WPF 动态设置菜单，非MVVM模式

随手建了WPF窗口

<Window x:Class="WpfAppTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfAppTest"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Menu x:Name="MenuControl" Background="Transparent" >
          
        </Menu>
 
    </Grid>
</Window>

后台代码

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            List<MenuItem> menuItems = new List<MenuItem>();
            MenuItem a = new MenuItem();
            a.Header = "A";
            a.Items.Add(new MenuItem { Header = "AAA" });
            menuItems.Add(a);
            menuItems.ForEach(menuItem => MenuControl.Items.Add(menuItem));
           

        }
    }
