WPF應用要實現最小化至系統托盤運行需要使用WinForm中的方法。

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

        #region 最小化系統托盤
        private void InitialTray()
        {
            //隱藏主窗體
            this.Visibility = Visibility.Hidden;
            //設置托盤的各個屬性
            _notifyIcon = new NotifyIcon();
            _notifyIcon.BalloonTipText = "服務運行中..."
 
;//托盤氣泡顯示內容
            _notifyIcon.Text = "ServerApp";
            _notifyIcon.Visible = true;//托盤按鈕是否可見
            _notifyIcon.Icon = new Icon(@"logo.ico");//托盤中顯示的圖標
            _notifyIcon.ShowBalloonTip(2000);//托盤氣泡顯示時間
            _notifyIcon.MouseDoubleClick += notifyIcon_MouseDoubleClick;
            //窗體狀態改變時觸發
            this.StateChanged += MainWindow_StateChanged;
        }
        #endregion
 


        #region 窗口狀態改變
        private void MainWindow_StateChanged(object sender, EventArgs e)
        {
            if (this.WindowState == WindowState.Minimized)
            {
                this.Visibility = Visibility.Hidden;
            }
        }
        #endregion

        #region 托盤圖標鼠標單擊事件
        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
    }
}
