1.拉出一个notifyIcon1到用户界面，也可以NEW一个

2.拉出一个ContextMenuStrip控件，命名为mymenu,集合中增加退出

3.notifyIcon1的属性ContextMenuStrip 增加 myMenu;或者this.notifyIcon1.ContextMenuStrip = myMenu;

        private void FrmMain_Load(object sender, EventArgs e)        {            //最小化到托盘           // this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);           // notifyIcon1.Icon = new Icon("2221.ico");//指定一个图标                  notifyIcon1.Visible = false;            notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);            this.SizeChanged += new System.EventHandler(this.FrmMain_SizeChanged);        }

        /// <summary>        /// 窗体大小改变事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void FrmMain_SizeChanged(object sender, EventArgs e)        {            if (this.WindowState == FormWindowState.Minimized)//最小化                  {                this.ShowInTaskbar = false;                this.notifyIcon1.Visible = true;            }        }        /// <summary>        /// 关闭窗体事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void FrmMain_FormClosing(object sender, FormClosingEventArgs e)        {            DialogResult result = MessageBox.Show("是否退出？选否,最小化到托盘", "操作提示", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);            if (result == DialogResult.Yes)            {                this.Dispose();                Application.Exit();            }            else            {                e.Cancel = true;                this.WindowState = FormWindowState.Minimized;                this.Visible = false;                this.notifyIcon1.Visible = true;            }        }        /// <summary>        /// 最小化图标鼠标事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)        {            if (e.Button == MouseButtons.Right)            {                myMenu.Show();            }        }        /// <summary>        /// 退出事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)        {            this.Dispose();            Application.Exit();        }
