WPF初探——利用Winform库中的NotifyIcon实现托盘小程序-优快云博客

本文介绍了一种在.NET中自定义NotifyIcon（托盘图标）的方法，并提供了完整的代码示例，包括如何设置托盘图标的属性、响应鼠标点击事件及关联菜单等。

前天晚上睡觉前萌生实现一个小软件的想法，界面准备采用类似Demon tools的NotifyIcon界面。今天游玩归来准备动手写的时候，在工具栏里面却发现没找到托盘控件，囧。既然没有，就自己实现下吧，参考了MSDN上给出的代码样板，于是写了如下一个，也算是为下一个小软件做下铺垫吧~

运行界面如下所示：

代码很少，如下所示：

using System;
using System.Windows;
using System.Windows.Forms;
using System.Drawing;

namespace Royen
{
     public partial class SysTray : Window
    {
         private NotifyIcon notifyIcon = null ;

         public SysTray()
        {
            InitializeComponent();

            InitialTray();
        }

         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 = " systray runnning... " ;
            notifyIcon.Text = " systray " ;
            notifyIcon.Icon = new System.Drawing.Icon( " http://www.cnblogs.com/res/spring.ico " );
            notifyIcon.Visible = true ;
            notifyIcon.ShowBalloonTip( 2000 );
            notifyIcon.MouseClick += new System.Windows.Forms.MouseEventHandler(notifyIcon_MouseClick);

             // 设置菜单项
            MenuItem setting1 = new MenuItem( " setting1 " );
            MenuItem setting2 = new MenuItem( " setting2 " );
            MenuItem setting = new MenuItem( " setting " , new MenuItem[]{setting1,setting2});

             // 帮助选项
            MenuItem help = new MenuItem( " help " );

             // 关于选项
            MenuItem about = new MenuItem( " about " );

             // 退出菜单项
            MenuItem exit = new MenuItem( " exit " );
            exit.Click += new EventHandler(exit_Click);

             // 关联托盘控件
            MenuItem[] childen = new MenuItem[] {setting,help,about,exit};
            notifyIcon.ContextMenu = new ContextMenu(childen);

             // 窗体状态改变时候触发
             this .StateChanged += new EventHandler(SysTray_StateChanged);
        }
