如何将WPF ContextMenu与NotifyIcon结合使用

Question

当用户单击系统托盘图标时，我想打开一个WPF ContextMenu。对于Windows，这是直截了当的，只需调用notifyIcon.ContextMenu = contextMenu就可以了.

在WPF上，我们不能轻松地设置ContextMenu，因为WPF的ContextMenu类与表单ContextMenu无关。我一直在追求的另一种选择是处理NotifyIcon的Click事件来打开WPF样式的ContextMenu。

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

        // This is intended to be a system tray application so we hide the window
        this.Visibility = Visibility.Hidden;

        // Winform context menu
        // The context menu closes when the user clicks anywhere outside the menu
        // The user can navigate the menu with the keyboard arrows and close with ESC
        var notifyIcon1 = new System.Windows.Forms.NotifyIcon();
        var contextMenu = new System.Windows.Forms.ContextMenu();
        var menuItem = new System.Windows.Forms.MenuItem();
        menuItem.Text = "WinForm Menu Item";
        contextMenu.MenuItems.Add(menuItem);
        notifyIcon1.ContextMenu = contextMenu;
        notifyIcon1.Icon = Properties.Resources.ico;
        notifyIcon1.Visible = true;

        // WPF context menu
        // The user cannot close the menu by clicking outside its bounds
        // Does not detect any keyboard input
        var notifyIcon2 = new System.Windows.Forms.NotifyIcon();
        notifyIcon2.Icon = Properties.Resources.ico;
        notifyIcon2.Visible = true;
        notifyIcon2.Click += NotifyIcon2_Click;
    }

    private void NotifyIcon2_Click(object sender, EventArgs e)
    {
        var contextMenu = new ContextMenu();
        var menuItem = new MenuItem();
        menuItem.Header = "WPF Menu Item";
        contextMenu.Items.Add(menuItem);
        contextMenu.IsOpen = true;
    }
}

这种方法的问题是，WPF ContextMenu从来没有收到任何提示，表明用户已经离开菜单导航并应该关闭(例如，当用户单击菜单边界之外时)。任何焦点或MouseCapture事件都不会被触发，除了单击其中一项之外，我无法关闭菜单。

因此，这里的问题(稍微不同)是:如何使用WPF的ContextMenu正确地模拟NotifyIcon的ContextMenu关闭行为？

我也面临着类似的问题。如果你想的话你可以试试

notifyIcon1.ContextMenuStrip = new Forms.ContextMenuStrip();
notifyIcon1.ContextMenuStrip.Items.Add("YourMenuItem",null, MenuItemEvent);

我希望这样可以解决问题。
