WPF应用最小化至系统托盘运行

WPF应用要实现最小化至系统托盘运行需要使用WinForm中的方法。

using System.Windows.Forms;
namespace ServerApp
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        private NotifyIcon _notifyIcon = null;
        public MainWindow()
        {
            InitializeComponent();
            InitialTray(); //最小化至托盘
        }

        #region 最小化系统托盘
        private void InitialTray()
        {
            //隐藏主窗体
            this.Visibility = Visibility.Hidden;
            //设置托盘的各个属性
            _notifyIcon = new NotifyIcon();
            _notifyIcon.BalloonTipText = "服务运行中...";//托盘气泡显示内容
            _notifyIcon.Text = "ServerApp";
            _notifyIcon.Visible = true;//托盘按钮是否可见
            _notifyIcon.Icon = new Icon(@"logo.ico");//托盘中显示的图标
            _notifyIcon.ShowBalloonTip(2000);//托盘气泡显示时间
            _notifyIcon.MouseDoubleClick += notifyIcon_MouseDoubleClick;
            //窗体状态改变时触发
            this.StateChanged += MainWindow_StateChanged;
        }
        #endregion

        #region 窗口状态改变
        private void MainWindow_StateChanged(object sender, EventArgs e)
        {
            if (this.WindowState == WindowState.Minimized)
            {
                this.Visibility = Visibility.Hidden;
            }
        }
        #endregion

        #region 托盘图标鼠标单击事件
        private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                if (this.Visibility == Visibility.Visible)
                {
                    this.Visibility = Visibility.Hidden;
                }
                else
                {
                    this.Visibility = Visibility.Visible;
                    this.Activate();
                }
            }
        }
        #endregion
    }
}
