读APPSETTING行简单:
 _nowVersion = ConfigurationManager.AppSettings["nowVersion"];

    以前与配制通过操作XML文件来进行,现在可以修改为以下方式:

 ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();
            filemap.ExeConfigFilename = "AupdateConsole.exe.config";
            Configuration config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);

            config.AppSettings.Settings["nowVersion"].Value = _nowVersion;
            config.AppSettings.Settings["siteCode"].Value = _siteCode;
            config.AppSettings.Settings["siteName"].Value = _siteName;
            config.AppSettings.Settings["appId"].Value = _appId;
            config.AppSettings.Settings["appCode"].Value = _appCode;
            config.Save();
            return true;
