class Program { private static Logger logger = LogManager.GetCurrentClassLogger(); //Logger对象代表与当前类相关联的日志消息的来源 static void Main(string[] args) { logger.Trace("输出一条记录信息成功!");//最常见的记录信息,一般用于普通输出 logger.Debug("输出一条Debug信息成功!"); //同样是记录信息,不过出现的频率要比Trace少一些,一般用来调试程序 logger.Info("输出一条消息类型信息成功!");//信息类型的消息 logger.Warn("输出一条警告信息成功");//警告信息,一般用于比较重要的场合 logger.Error("输出一条错误信息成功!");//错误信息 logger.Fatal("输出一条致命信息成功!");//致命异常信息。一般来讲,发生致命异常之后程序将无法继续执行。 Console.WriteLine("11111111"); } }
