log4net配置

1.configuration配置

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

2.Global.asax

            //加载log4配置
            log4net.Config.XmlConfigurator.Configure();
        }

3.configuration的log4net节点

  <log4net>
    <logger name="wolflogInfo">
      <level value="Info" />
      <appender-ref ref="wolflogInfoFileAppender" />
    </logger>
    <logger name="wolflogError">
      <level value="Error" />
      <appender-ref ref="wolflogErrorFileAppender" />
    </logger>
    <logger name="wolflogALL">
      <level value="ALL" />
      <appender-ref ref="wolflogALLFileAppender" />
    </logger>
    <!-- 绑定使用的名称 -->　　
    <appender name="wolflogInfoFileAppender" type="log4net.Appender.RollingFileAppender,log4net">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <!--输出文件夹路径-->
      <param name="File" type="" value="App_Data/Log/Info/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <!--文件名称命名规则-->
      <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
      <param name="StaticLogFileName" value="false" />
      <param name="MaxSizeRollBackups" value="62" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <!--输出头-->
        <param name="ConversionPattern" value="%n[%d] %c %n%m%n%n" />
      </layout>
    </appender>
    <appender name="wolflogErrorFileAppender" type="log4net.Appender.RollingFileAppender,log4net">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <param name="File" type="" value="App_Data/Log/Error/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
      <param name="StaticLogFileName" value="false" />
      <param name="MaxSizeRollBackups" value="62" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%n[%d] %c %n%m%n%n" />
      </layout>
    </appender>
    <appender name="wolflogALLFileAppender" type="log4net.Appender.RollingFileAppender,log4net">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <param name="File" type="" value="App_Data/Log/ALL/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
      <param name="StaticLogFileName" value="false" />
      <param name="MaxSizeRollBackups" value="62" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%n[%d] %c %n%m%n%n" />
      </layout>
    </appender>
  </log4net>

4.调用

            ILog log = log4net.LogManager.GetLogger("wolflogInfo");
            log.Info("输出点东西Info");
            log.Error("输出点东西Error");
            ILog log1 = log4net.LogManager.GetLogger("wolflogError");
            log1.Info("输出点东西Info");
            log1.Error("输出点东西Error");
            ILog log2 = log4net.LogManager.GetLogger("wolflogALL");
            log2.Info("输出点东西Info");
            log2.Error("输出点东西Error");
