最小化时托盘

需要加一个    notifyIcon1控件，希望设置图标，最后就可以加下面2个事件就行了

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            this.TopMost = true;
            this.Show();
            this.notifyIcon1.Visible = false;
            this.WindowState = FormWindowState.Normal;
        }

        private void Form3_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.Hide();
                this.notifyIcon1.Visible = true;
            }

        }
