Log4Net配置

1.Install-Package log4net

2.命名空间前添加XmlConfiguratorAttribute标记:[assembly: log4net.Config.XmlConfigurator(Watch = true)],或添加到AssemblyInfo.cs

3.web.config配置

在<configuration></configuration>里添加,

 <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    <section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
  </configSections>
  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <!--日志路径-->
      <param name= "File" value= "D:\\log\\"/>
      <!--是否是向文件中追加日志-->
      <param name= "AppendToFile" value= "true"/>
      <!--log保留天数-->
      <param name= "MaxSizeRollBackups" value= "10"/>
      <!--日志文件名是否是固定不变的-->
      <param name= "StaticLogFileName" value= "false"/>
      <!--日志文件名格式为:2017-07-25.log-->
      <param name= "DatePattern" value= "yyyy-MM-dd".log""/>
      <!--日志根据日期滚动-->
      <param name= "RollingStyle" value= "Date"/>
      <!--日志文本格式-->
      <layout type="log4net.Layout.PatternLayout">
        <!--例:2017-07-25 10:56:15,506 [9] INFO  Log4NetSample.Program 18 - 消息 -->
        <!--%d  时间-->
        <!--%t  线程-->
        <!--%-5p  日志级别-->
        <!--%c  出错类-->
        <!--%L  出错行-->
        <!--%m  日志信息-->
        <!--%n  换行-->
        <param name="ConversionPattern" value="%d [%t] %-5p %c %L - %m %n" />
      </layout>
    </appender>

    <root>
      <!--(高) OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL (低) -->
      <level value="all" />
      <appender-ref ref="RollingLogFileAppender"/>
    </root>
  </log4net>

4.使用

  

  var log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            log.Info("消息");
            log.Warn("警告");
            log.Error("异常");
            log.Fatal("错误");

5.结果
