Question

我希望我提出正确的问题，但这是我的情况。我有TreeViewItem我正在实施。在其中我设置/添加各种属性，其中一个是ContextMenu。我想要做的就是将MenuItems添加到ContextMenu而不传递给函数等。

以下是我如何使用TreeViewItem实施ContextMenu：

public static TreeViewItem Item = new TreeViewItem() //Child Node
{
        ContextMenu = new ContextMenu //CONTEXT MENU
        {
            Background = Brushes.White,
            BorderBrush = Brushes.Black,
            BorderThickness = new Thickness(1),

            //**I would like to add my MENUITEMS here if possible
        }
};

非常感谢！

为此目的WPF我这样做了：

TreeViewItem GreetingItem = new TreeViewItem()
    {
        Header = "Greetings",
        ContextMenu = new ContextMenu //CONTEXT MENU
        {
            Background = Brushes.White,
            BorderBrush = Brushes.Black,
            BorderThickness = new Thickness(1),
        }
    };

// Create ContextMenu
contextMenu = new ContextMenu();
contextMenu.Closing += contextMenu_Closing;

// Exit item
MenuItem menuItemExit = new MenuItem
{
      Header = Cultures.Resources.Exit,
      Icon= Cultures.Resources.close
};
menuItemExit.Click += (o, a) =>
{
     Close();
}

// Restore item
MenuItem menuItemRestore = new MenuItem
{
    Header = Cultures.Resources.Restore,
    Icon= Cultures.Resources.restore1
};
menuItemRestore.Click += (o, a) =>
{
     WindowState = WindowState.Normal;
};

contextMenu.Items.Add(menuItemRestore);
contextMenu.Items.Add(menuItemExit);               

GreetingItem.ContextMenu = contextMenu;

您可以将其设置为支持的任何元素。

编辑：我是通过记忆来写的，抱歉，如果不准确的话。但或多或少是这个想法。

Sonhja的回答是正确的。为您的案例提供一个示例。

        TreeViewItem GreetingItem = new TreeViewItem()
        {
            Header = "Greetings",
            ContextMenu = new ContextMenu //CONTEXT MENU
            {
                Background = Brushes.White,
                BorderBrush = Brushes.Black,
                BorderThickness = new Thickness(1),
            }
        };

        MenuItem sayGoodMorningMenu = new MenuItem() { Header = "Say Good Morning" };
        sayGoodMorningMenu.Click += (o, a) =>
        {
            MessageBox.Show("Good Morning");
        };
        MenuItem sayHelloMenu = new MenuItem() { Header = "Say Hello" };
        sayHelloMenu.Click += (o, a) =>
            {
                MessageBox.Show("Hello");
            };
        GreetingItem.ContextMenu.Items.Add(sayHelloMenu);
        GreetingItem.ContextMenu.Items.Add(sayGoodMorningMenu);
        this.treeView.Items.Add(GreetingItem);

在实施过程中是否可以将菜单项添加到上下文菜单中？
