本文展示了一个使用C#编写的简单示例程序，该程序可以让窗体在屏幕中自动上升到顶部位置并停留，当窗体关闭时则自动下降直至消失。通过两个定时器分别控制窗体的上升和下降过程。

        Timer timer_Up = new Timer();
        Timer timer_Down = new Timer();

        private void Form1_Load(object sender, EventArgs e)
        {
            this.Left = Screen.PrimaryScreen.WorkingArea.Width - this.Width - 1;
            this.Top = Screen.PrimaryScreen.WorkingArea.Bottom;
            timer_Up.Interval = 10;
            timer_Up.Tick += timer_Up_Tick;
            timer_Up.Enabled = true;
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            timer_Down.Interval = 10;
            timer_Down.Tick += timer_Down_Tick;
            timer_Down.Enabled = true;
            e.Cancel = true;
        }

        private void timer_Up_Tick(object sender, EventArgs e)
        {
            if (this.Bottom <= Screen.PrimaryScreen.WorkingArea.Bottom)
            {
                this.Top = Screen.PrimaryScreen.WorkingArea.Bottom - this.Height - 1;
                timer_Up.Enabled = false;
                return;
            }
            this.Top -= 10;
        }

        private void timer_Down_Tick(object sender, EventArgs e)
        {
            if (this.Top >= Screen.PrimaryScreen.Bounds.Bottom)
            {
                timer_Down.Enabled = false;
                Environment.Exit(0);
                return;
            }
            this.Top += 10;
        }
