The following is an online example written by a netizen, reference the same meaning, the original address http://www.cnblogs.com/txw1958/archive/2013/01/16/csharp-xml.html

         Public voidCreateFile () {//join the declaration paragraph of XML, <?xml version= "1.0" encoding= "gb2312"?>XmlDeclaration xmldecl = xmldoc. Createxmldeclaration ("1.0",NULL,NULL);//encoding mode: "gb2312", "Utf-8", can also be nullxmldoc.            AppendChild (XMLDECL); //Add a root elementXmlelem = xmldoc. CreateElement ("","Configuration",""); XmlDoc.            AppendChild (Xmlelem); //add a different element             for(inti =1; I <3; i++) {XmlNode root= xmldoc. selectSingleNode ("Employees");//Find <Employees>XmlElement xe1 = xmldoc. CreateElement ("Node");//Create a <Node> nodeXe1. SetAttribute ("genre","Doucube");//set the node genre propertyXe1.
