如何在WPF NotifyIcon中将单击事件添加到上下文菜单按钮？

<tb:TaskbarIcon x:Name="notifyIcon">
    <tb:TaskbarIcon.ContextMenu>
        <ContextMenu>
            <MenuItem Header="菜单项1" Click="MenuItem_Click" />
            <MenuItem Header="菜单项2" Click="MenuItem_Click" />
        </ContextMenu>
    </tb:TaskbarIcon.ContextMenu>
</tb:TaskbarIcon>

private void MenuItem_Click(object sender, RoutedEventArgs e)
{
    MenuItem menuItem = sender as MenuItem;
    string header = menuItem.Header.ToString();

    // 根据菜单项的Header进行不同的操作
    switch (header)
    {
        case "菜单项1":
            // 处理菜单项1的逻辑
            break;
        case "菜单项2":
            // 处理菜单项2的逻辑
            break;
        default:
            break;
    }
}

notifyIcon.Icon = new System.Drawing.Icon("icon.ico");
