        需要先添加引用System.Configuration.dll文件

        ExeConfigurationFileMap map = new ExeConfigurationFileMap();
        map.ExeConfigFilename = @"E:\aaa\bbb.exe.config"; ;
        Configuration config = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
        string version = config.AppSettings.Settings["version"].Value;
