WinForm中实现最小化到系统托盘

有个叫NotifyIcon的控件

１、建个WinForm项目，其它操作略过。 ２、拉个NotifyIcon控件，将属性Visable设置成False，在Text属性上随便填些文件。 ３、实现Form的SizeChanged事件，代码如下： if(this.WindowState == FormWindowState.Minimized)  //判断是否最小化 {    this.ShowInTaskbar = false;  //不显示在系统任务栏      notifyIcon.Visible = true;  //托盘图标可见 } ４、实现NotifyIcon控件的DoubleClick事件，代码如下： if(this.WindowState == FormWindowState.Minimized){    this.ShowInTaskbar = true;  //显示在系统任务栏     this.WindowState = FormWindowState.Normal;  //还原窗体      notifyIcon.Visible = false;  //托盘图标隐藏 }

例题：

private ContextMenu notifyiconMnu;

#region 最小化到任务栏        /// <summary>        /// 最小化到任务栏        /// </summary>        private void Initializenotifyicon()        {            //定义一个MenuItem数组，并把此数组同时赋值给ContextMenu对象             MenuItem[] mnuItms = new MenuItem[3];            mnuItms[0] = new MenuItem();            mnuItms[0].Text = "显示窗口";            mnuItms[0].Click += new System.EventHandler(this.notifyIcon1_showfrom);

            mnuItms[1] = new MenuItem("-");

            mnuItms[2] = new MenuItem();            mnuItms[2].Text = "退出系统";            mnuItms[2].Click += new System.EventHandler(this.ExitSelect);            mnuItms[2].DefaultItem = true;

            notifyiconMnu = new ContextMenu(mnuItms);            notifyIcon1.ContextMenu = notifyiconMnu;            //为托盘程序加入设定好的ContextMenu对象         }

        private void notifyIcon1_DoubleClick(object sender, EventArgs e)        {            if (this.WindowState == FormWindowState.Minimized)            {                this.Show();                this.ShowInTaskbar = true;                 this.WindowState = FormWindowState.Normal;                 notifyIcon1.Visible = false;             }        }

        public void notifyIcon1_showfrom(object sender, System.EventArgs e)        {            if (this.WindowState == FormWindowState.Minimized)            {                this.Show();                this.ShowInTaskbar = true;                this.WindowState = FormWindowState.Normal;                notifyIcon1.Visible = false;            }        }

        public void ExitSelect(object sender, System.EventArgs e)        {            //隐藏托盘程序中的图标             notifyIcon1.Visible = false;            //关闭系统             this.Close();            this.Dispose(true);        }

        #endregionprivate void Form_main_SizeChanged(object sender, EventArgs e)        {            if (this.WindowState == FormWindowState.Minimized) //判断是否最小化            {                notifyIcon1.Visible = true;                this.Hide();                this.ShowInTaskbar = false;

                Initializenotifyicon();            }        }
