        this.Close();

        Graph1 graph = new Graph1();
        graph.Show();

您所要做的就是将Refresh Form（）更改为Refresh（）;并清除函数Refresh Form（）。

    private void Graph_Load(object sender, EventArgs e)
    {
        {
            System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();

            label1.Text = DateTime.Now.ToString("HH:mm:ss");

            timer1.Interval = 60000;//1 minutes
            timer1.Tick += new System.EventHandler(Timer1_Tick);
            timer1.Start();
        }
    }

    private void Timer1_Tick(object sender, EventArgs e)
    {
        label1.Text = DateTime.Now.ToString("HH:mm:ss");
        Refresh(); // OR Invalidate(); OR Update();
    }     

这里label1是一个简单的手表，看看每分钟刷新的形式
