//XML的创建

       /// <summary>
       /// 创建新的XML
       /// </summary>

        public void CreateNewXml(string updateXml)

            XmlDocument xmldoc = new XmlDocument();//表示 XML 文档。

            //xmldoc.CreateNode创建一个XmlNode节点
            XmlNode xmlNode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration,"","");//创建XML声明
            xmldoc.AppendChild(xmlNode);

XML的写入：

        /// 向新的XML中写入信息， updateName参数是需要更新的文件对象，updateNamePath参数是更新对象的相对路径
        /// </summary>
        /// <param name="updateName"></param>
        /// <param name="updateNamePath"></param>
        public void WriteToNewXml(string updateName, string updateNamePath,string updateXml)
        {

            XmlDocument xd = new XmlDocument();
            xd.Load(updateXml);
            XmlNode root = xd.DocumentElement;

            XmlElement objectInfo = xd.CreateElement("objectInfo");
            objectInfo.SetAttribute("genre", updateNamePath);
            objectInfo.SetAttribute("isDir", "0");

            XmlElement updateObject = xd.CreateElement("updateObject");
            updateObject.InnerText = updateName;
            objectInfo.AppendChild(updateObject);

            XmlElement updateObjectPath = xd.CreateElement("updateObjectPath");
            updateObjectPath.InnerText = updateNamePath;
            objectInfo.AppendChild(updateObjectPath);

            XmlElement updateObjectServerPath = xd.CreateElement("updateObjectServerPath");//创建一个节点
            updateObjectServerPath.InnerText = "url";
            objectInfo.AppendChild(updateObjectServerPath);

XML的读取：

                 {
                     string FileFullPath = gameRootPath + xeObjectInfo.GetAttribute("genre");

                      FileFullPath += ("\\"+ xeObjectInfo["updateObject"].InnerText);
                      makeIndexDirPath += xeObjectInfo.GetAttribute("genre");//读取genre属性
                      createdir(makeIndexDirPath);
