namespace notify
{

        public Form1()
        {
            InitializeComponent();
            this.SizeChanged += new EventHandler(Form1_SizeChanged);
        }

        void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.Hide();

        {

                this.Show();
                this.WindowState = FormWindowState.Normal;
            }
            else
            {
                Point pt = new Point();
                pt = Control.MousePosition;
                contextMenuStrip1.Show(pt);
            }
        }

        private void ToolStripMenuItem_Show_Click(object sender, EventArgs e)
        {
            this.Show();
            this.WindowState = FormWindowState.Normal;
        }

        private void ToolStripMenuItem_Exit_Click(object sender, EventArgs e)
        {
            notifyIcon1 = null;
            this.Close();
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (notifyIcon1 != null)
            {
                e.Cancel = true;
                this.Visible = false;
            }
        }
    }
}

一个简单类似win7任务栏的功能就实现了
