 public string ReadConfig()

        {

            List<string> list = new List<string>();

            ExeConfigurationFileMap file = new ExeConfigurationFileMap();

            file.ExeConfigFilename = System.Windows.Forms.Application.ExecutablePath + ".config";

            Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(file, ConfigurationUserLevel.None);



            var myApp = (AppSettingsSection)config.GetSection("appSettings");

            return myApp.Settings["lcc"].Value;

     

        }



        public string WriteConfig(string val)

        {

            ExeConfigurationFileMap file = new ExeConfigurationFileMap();

            file.ExeConfigFilename = System.Windows.Forms.Application.ExecutablePath + ".config";

            Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(file, ConfigurationUserLevel.None);



            var myApp = (AppSettingsSection)config.GetSection("appSettings");

            myApp.Settings["lcc"].Value = val;

            config.Save();

            return val;
