            XmlDocument xml = new XmlDocument();

            xml.Load(Server.MapPath("~/xml/xixi.xml"));

            XmlNode trackList = xml.SelectSingleNode("trackList");

            XmlElement track = xml.CreateElement("track");

            XmlElement title = xml.CreateElement("title");

            XmlElement creator = xml.CreateElement("creator");

            XmlElement location = xml.CreateElement("location");

            track.SetAttribute("indx", "11");

            track.AppendChild(title);

            track.AppendChild(creator);

            track.AppendChild(location);

            trackList.AppendChild(track);

            xml.Save(Server.MapPath("~/xml/xixi.xml"));

想在trackList插入和里面一样结构的track节点
出错未将对象引用设置到对象的实例。
高手来！！！！
