原文:WPF 学习笔记－在WPF下创建托盘图标

首先需要在项目中引用System.Windows.Forms，System.Drawing;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

using System.Drawing;

namespace WpfApplication1

{

    ///

    /// Interaction logic for MainWindow.xaml

    ///

    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(System.Windows.Forms.Application.StartupPath + \"\\\\wp.ico\");

            notifyIcon.Visible = true;

            notifyIcon.ShowBalloonTip(2000);

            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);

        }

        ///

        /// 窗体状态改变时候触发

        ///

        ///

        ///

        private void SysTray_StateChanged(object sender, EventArgs e)

        {

            if (this.WindowState == WindowState.Minimized)

            {

                this.Visibility = Visibility.Hidden;

            }

        }

        ///

        /// 退出选项

        ///

        ///

        ///

        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();

            }

        }

        ///

        /// 鼠标单击

        ///

        ///

        ///

        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.Activate();

                }

            }

        }

    }

}

以上代码并非用户控件代码，只需加在主窗体中即可。
