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");
