子窗体中写了一个定时开关机的timertick，现在的问题是关闭了当前的子窗体后timer就不会执行了，怎么让timer能够在子窗体关闭后任然运行
private void timer1_Tick(object sender, EventArgs e)
{

        reader();
        if (cycle == 0)
        {
            closetype();
        }
        else
        {
            int nowWeek = DateTime.Now.DayOfWeek.GetHashCode();
            if (nowWeek == cycle)
            {
               closetype();
            }

        }
    }
