生成XML、讀取XML

生成XML方法：

 XmlDocument xml = new XmlDocument();
                           
                //插入聲明
                XmlDeclaration xmlDelaration = xml.CreateXmlDeclaration("1.0", "UTF-8", null);
                XmlElement root = xml.DocumentElement;
                xml.InsertBefore(xmlDelaration, root);

                XmlElement node_Results = xml.CreateElement("Results");
                xml.AppendChild(node_Results);

 return xml.InnerXml;

或者:

  XmlDocument xmldoc = new XmlDocument();
            xmldoc.LoadXml("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Results></Results>");

 XmlNodeList nodeList = xmldoc.GetElementsByTagName("Results");
                    XmlNode node_results = null;
                    if (nodeList.Count > 0)
                    {
                        node_results = nodeList[0];
                    }

//屬於Attributes添加方法:

XmlAttribute _ShipLotNo = xml.CreateAttribute("ShipLotNo");
_ShipLotNo.Value = lot.Info.ssl_iShipLotNo.ToString();
node_OrderItem.Attributes.Append(_ShipLotNo);

 return xmldoc.InnerXml;

讀取XML方法:
