WPF 程序启动显示为通知区域的图标方法

首先需要引用  System.Windows;  System.Drawing;

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            InitialTray();
        }
         private System.Windows.Forms.NotifyIcon notifyIcon = null;
        private void InitialTray()
        {
 
            //设置托盘的各个属性
            notifyIcon = new System.Windows.Forms.NotifyIcon();
            notifyIcon.BalloonTipText = "程序开始运行";
            notifyIcon.Text = "托盘图标";
            notifyIcon.Icon = new System.Drawing.Icon("NotifyIcon.ico");
            notifyIcon.Visible = true;
            notifyIcon.ShowBalloonTip();
            notifyIcon.MouseClick += new System.Windows.Forms.MouseEventHandler(notifyIcon_MouseClick);
 
            //设置菜单项
            System.Windows.Forms.MenuItem menu1 = new System.Windows.Forms.MenuItem("菜单项1");
            System.Windows.Forms.MenuItem menu2 = new System.Windows.Forms.MenuItem("菜单项2");
            System.Windows.Forms.MenuItem menu = new System.Windows.Forms.MenuItem("菜单", new System.Windows.Forms.MenuItem[] { menu1 , menu2 });
 
            //退出菜单项
            System.Windows.Forms.MenuItem exit = new System.Windows.Forms.MenuItem("exit");
            exit.Click += new EventHandler(exit_Click);
 
            //关联托盘控件
            System.Windows.Forms.MenuItem[] childen = new System.Windows.Forms.MenuItem[] { menu , exit };
            notifyIcon.ContextMenu = new System.Windows.Forms.ContextMenu(childen);
 
            //窗体状态改变时候触发
            this.StateChanged += new EventHandler(SysTray_StateChanged);
        }
       /// <summary>
        /// 窗体状态改变时候触发
       /// </summary>

       /// <param name="e"></param>
        private void SysTray_StateChanged(object sender, EventArgs e)
        {
            if (this.WindowState == WindowState.Minimized)
            {
 
                //this.Visibility = Visibility.Hidden;
            }
        }
 
        /// <summary>
        /// 退出选项
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
 
        private void exit_Click(object sender, EventArgs e)
        {
            if (System.Windows.MessageBox.Show("确定要关闭吗?", "退出", MessageBoxButton.YesNo,MessageBoxImage.Question,MessageBoxResult.No) == MessageBoxResult.Yes)
            {
                notifyIcon.Dispose();
                System.Windows.Application.Current.Shutdown();
            }
        }
 
      /// <summary>
        /// 鼠标单击
      /// </summary>
      /// <param name="sender"></param>
      /// <param name="e"></param>
 
        private void notifyIcon_MouseClick(object sender, System.Windows.Forms.MouseEventArgs e)
        {
            if (e.Button == System.Windows.Forms.MouseButtons.Left)
            {
                if (this.Visibility == Visibility.Visible)
                {
                    //this.Visibility = Visibility.Hidden;
                }
                else
                {
                    this.Visibility = Visibility.Visible;
                    this.WindowState = WindowState.Normal;
                    //this.Activate();
                }
            }
        }
　　　　// 改变窗体关闭按钮事件
        private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            e.Cancel = true;//取消窗体关闭

    }
