用C#创建XML

            XmlDocument doc = new XmlDocument();            XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "GB2312", null);            doc.AppendChild(dec);            //创建一个根节点（一级）            XmlElement root = doc.CreateElement("First");            doc.AppendChild(root);            //创建节点（二级）            XmlNode node = doc.CreateElement("Seconde");            //创建节点（三级）            XmlElement element1 = doc.CreateElement("Third1");            element1.SetAttribute("Name", "Sam");            element1.SetAttribute("ID", "665");            element1.InnerText = "Sam Comment";            node.AppendChild(element1);            XmlElement element2 = doc.CreateElement("Third2");            element2.SetAttribute("Name", "Round");            element2.SetAttribute("ID", "678");            element2.InnerText = "Round Comment";            node.AppendChild(element2);                       root.AppendChild(node);            doc.Save(@"d:\bb.xml");            Console.Write(doc.OuterXml);
