1.NuGet安装log4net.
2.修改配置文件
<?xml version="1.0"?><configuration> ?<configSections> ???<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> ?</configSections> ?<log4net> ???<!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL --> ???<!-- Set root logger level to ERROR and its appenders --> ???<root> ?????<level value="ALL"/> ?????<appender-ref ref="SysAppender"/> ???</root> ???<!-- Print only messages of level DEBUG or above in the packages --> ???<logger name="WebLogger"> ?????<level value="ALL"/> ???</logger> ???<appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net" > ?????<param name="File" value="Logger/" /> ?????<param name="AppendToFile" value="true" /> ?????<param name="RollingStyle" value="Date" /> ?????<param name="DatePattern" value=""Logs_"yyyyMMdd".txt"" /> ?????<param name="StaticLogFileName" value="false" /> ?????<layout type="log4net.Layout.PatternLayout,log4net"> ???????<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> ???????<param name="Header" value="----------------------header--------------------------" /> ???????<param name="Footer" value="----------------------footer--------------------------" /> ?????</layout> ???</appender> ?</log4net></configuration>
3.AssemblyInfo.cs中加入代码
// 日志组件配置
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", ConfigFileExtension = "config", Watch = true)]
4.公共类封装方法调用log4net
