主窗体和子窗体之间的转换

其实就是把子窗体的FormClosing事件写在主窗体中

  private void BtnFeedMaster_Click(object sender, EventArgs e)

        {
            //Feeder注册
            Feeder_Master_Add Feeder_Master_Add = new Feeder_Master_Add("INSTER");
            Feeder_Master_Add.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen; //子窗体显示位置
            this.Hide();//主窗体隐藏
            Feeder_Master_Add.Show();
            Feeder_Master_Add.FormClosing += Feeder_Master_Add_FormClosing;
        }


        #endregion


        #region 子窗体关闭事件
        private void Feeder_Master_Add_FormClosing(object sender, FormClosingEventArgs e)
        {
            this.Show();
        }
