C#操作XML总结2

      继续说一下C#操作XML的相关内容，这次主要说一下运用 XmlSerializer类，主要是用于动态读取和修改XML。     
      实例如下：（这是一段升级配置文件）
      LocalUpdate.ini

      <?xml version="1.0" encoding="utf-8"?>
      <LocalConfig>  
        <SoftVersion>1.0.0.0</SoftVersion>
        <UpdatePublishTime>1.0.0.0</UpdatePublishTime>
        <ServerUrl>http://zorro/UpdateContent/</ServerUrl>
        <UpdateHistoryList>
          <LocalFile num="2009.3.20" lastver="这是最原始的Bata版本" />
        </UpdateHistoryList>
      </Config>

       使用类似结构体的类LocalConfig.cs,代码如下：
      

/// <summary>
    /// 读取主程序的升级配置文件(*.ini)
    /// </summary>
    public class LocalConfig
    {
        private string serverUrl = "";
        private string softVersion = string.Empty;
       // private UpdateHistoryList updateHistoryList = new UpdateHistoryList();
       // private string updateIntroduction = "";

        private string publishTime = "";
        /// <summary>
        /// 升级日期
        /// </summary>
        public string UpdatepublishTime { get { return publishTime; } set { publishTime = value; } }

        /// <summary>
        /// 升级网址URL
        /// </summary>
        public string ServerUrl { get { return serverUrl; } set { serverUrl = value; } }

        /// <summary>
        /// 软件版本号
        /// </summary>
        public string SoftVersion { get { return softVersion; } set { softVersion = value; } }

        /// <summary>
        /// 更新列表内容
        /// </summary>
        //public UpdateHistoryList UpdateHistory
        //{
        //    get { return updateHistoryList; }
        //    set { updateHistoryList = value; }
        //}

        public static LocalConfig LoadConfig(string file)
        {
            XmlSerializer xs = new XmlSerializer(typeof(LocalConfig));
            StreamReader sr = new StreamReader(file);
            LocalConfig config = xs.Deserialize(sr) as LocalConfig;
            sr.Close();

            return config;
        }

        public void SaveConfig(string file)
        {
            XmlSerializer xs = new XmlSerializer(typeof(LocalConfig));
            StreamWriter sw = new StreamWriter(file);
            xs.Serialize(sw, this);
            sw.Close();
        }
    }

   辅助类文件

    /// <summary>
    /// 升级文件说明
    /// </summary>
    public class LocalFile
    {
        private string num = "";
        private string content = "";

        [XmlAttribute("num")]
        public string Num { get { return num; } set { num = value; } }
        [XmlAttribute("content")]
        public string UpdateContent { get { return content; } set { content = value; } }

        public LocalFile(string num, string updateContent)
        {
            this.num = num;
            this.content = updateContent;
        }

        public LocalFile()
        {
        }

    }

     操作XML的调用代码：

            //判断本地升级文件是否存在
            strLocalUpdateFile = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "LocalUpdate.ini");
            if (!File.Exists(strLocalUpdateFile))
            {
                MessageBox.Show("本地升级配置文件损坏，无法升级！");
                this.Close();
                return;
            }

            //读取本地配置
            localUpdateConfig = LocalConfig.LoadConfig(strLocalUpdateFile);
            ////XML加密
            //xmlEncryptAndDecrypt.XmlEncrypt("LocalConfig");
            //本地版本
            this.lblCurVer.Text = localUpdateConfig.SoftVersion;

            //更新内容说明列表(暂时不实现)
            // List<UpdateHistoryList> historyList = new List<UpdateHistoryList>();

            //升级文件所在的文件夹
            string strRemoteDir = localUpdateConfig.ServerUrl;
            //获得服务器地址
            string serverUrl = GetServerUrl(strRemoteDir);
            if (serverUrl != "")
            {
                bCanUpdate = IsConnectServer(serverUrl);
            }
