Log4Net配置

上的日志将Debug、Error、Info、Warn的信息放在一个文件里，看着有些杂乱。我自己配置了一个将它们分开（今天双十一）放，看着舒服，下面是配置后得到效果

好了，接下来是步骤，

首先在 Nuget引用log4net包，此处内容跳过，

接下来是配置文件  控制台是App.config网站是web.config文件

1   <configSections> 
2     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
3   configSections>

  1 <log4net>

  3     <root>
  4       
  5       <level value="ERROR"/>
  6       <level value="WARN"/>
  7       <level value="INFO"/>
  8       <level value="DEBUG"/>
  9       <appender-ref ref="Error" />
 10       <appender-ref ref="Warn" />

日志的配置文件已经写好，接下来是使用

添加  

 [assembly:log4net.Config.XmlConfigurator()  ]

可以放在AssemblyInfo类里面，也可以在类的命名空间上面

调用测试  

1  var logger = LogManager.GetLogger(typeof(Program));
2             for (int i = 0; i < 100000; i++)
3             {
4             logger.Info("ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
5             logger.Error("ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
6             logger.Debug("ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
7             logger.Warn("ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
8 
9             }

好了，完成，留着给以后的自己看
