            try
            {
                int a = 1;
                int b = 0;
                int c = a / b;

            }
            catch(Exception ex)
            {
                Logger _logger = LogManager.GetCurrentClassLogger(); 
                //_logger.Trace("Trace Message"); 
                //_logger.Debug("DebugMessage"); 
                //_logger.Info("InfoMessage");
                _logger.Error(ex.Message+ex.StackTrace);
                //_logger.Fatal("FatalMessage");
