C# Winform 遍歷面板控件，寫入XML

源碼是：

void FindCtrlName(Control parent)//遍歷面板控件
        {
            foreach (Control ctrl in parent.Controls)
            {
                CtrlToXML(ctrl);
                if (ctrl.Controls.Count > 0)
                {
                    FindCtrlName(ctrl);
                }
            }
        }

        private void CtrlToXML(Control ctrl)//Linq to XML
        {
            XElement xe = XElement.Load(@"setting\test.xml");
            XElement record = new XElement(
                new XElement("controls",
                new XAttribute("type", ctrl.GetType().ToString()),
                new XAttribute("language", "Chinese"),
                new XAttribute("name", ctrl.Name),
                new XElement("title", ctrl.Text),
                new XElement("visible", ctrl.Visible),
                new XElement("enable", ctrl.Enabled),
                new XElement("value", 28.00)));

            xe.Add(record);
            xe.Save(@"setting\test.xml");
//            MessageBox.Show("插入成功！");
        }

我的面板得到的 XML 是：
