求大神帮我把这段代码改成方法或者函数，

        public static void FormHeleper
{
            //if (setadmin == null)
             //{
             //    setadmin = new setadmin();//将主窗体对象传递过去
            //    setadmin.TopLevel = false;
             //    setadmin.ForeColor = Color.Black;
             //    panel1.Controls.Add(setadmin);
             //    setadmin.Show();
             //    setadmin.BringToFront();
             //}
             //else if (!panel1.Controls.Contains(setadmin))
             //{
             //    setadmin = new setadmin();//将主窗体对象传递过去
            //    setadmin.TopLevel = false;
             //    setadmin.ForeColor = Color.Black;
             //    panel1.Controls.Add(setadmin);
             //    setadmin.Show();
             //    setadmin.BringToFront();
             //}
             //else
             //{
             //    setadmin.Activate();
             //    setadmin.BringToFront();
             //}
}封装一个静态的方法
