c#中程序最小化到托盘

拖一个 notifyIcon控件到界面，名为 notifyIcon1

      //窗体对应的事件

        #region Form1_SizeChanged

        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized) //判断是否最小化
            {
                this.ShowInTaskbar = false; //不显示在系统任务栏
                notifyIcon1.Visible = true; //托盘图标可见
                this.notifyIcon1.ShowBalloonTip(1000, this.notifyIcon1.BalloonTipTitle, this.notifyIcon1.BalloonTipText, ToolTipIcon.Info);//显示气泡提示
            }
        }
        #endregion

还可以设置 notifyIcon1 的事件

        #region notifyIcon1_DoubleClick
        private void notifyIcon1_DoubleClick(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.Show();
                this.WindowState = FormWindowState.Normal;
                //notifyIcon1.Visible = false; //托盘图标不可见
                this.ShowInTaskbar = true;
            }
        }
        #endregion

        #region notifyIcon1_MouseUp
        private void notifyIcon1_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                this.notifyIcon1.ShowBalloonTip(1000, "提示：", "系统当前时间：" + DateTime.Now.ToLocalTime().ToString() + "\r\n您设定的时间：" + txtTaskTime.Text, ToolTipIcon.Info);//显示气泡提示
            }

        }
        #endregion

总之，就是改变它在托盘的可见性和在任务栏的可见性。
