1 、[assembly: log4net.Config.XmlConfigurator(ConfigFile = "web.config", Watch = true)] 写到自定义的Log类中的AssemblyInfo.cs中
2、在需要使用log的项目中,配置其web.config文件
<configSections>
<!-- 添加log4net配置节 -->
<section name="
log4net" type="
log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<!-- 设置log4net配置节 -->
<log4net>
<!--输出到文件-->
<appender name="rollingFile" type="
log4net.Appender.RollingFileAppender,log4net" >
<param name="File" type="" value="
c:\testlog\log.txt" />
<param name="AppendToFile" value="true" />
<param name="StaticLogFileName" value="true" />
<!-- 滚动方式:按日期 -->
<param name="RollingStyle" value="Date" />
<param name="DatePattern" value="yyyyMMdd" />
<!-- 滚动方式:按日志大小
<param name="RollingStyle" value="Size"/>
<param name="MaxSizeRollBackups" value="100"/>
<param name="MaximumFileSize" value="2MB"/>
-->
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="Header" value=" ----------------------header-------------------------- " />
<param name="Footer" value=" ----------------------footer-------------------------- " />
<param name="ConversionPattern"
value="%n%date [线程ID:%thread] 文件:%file [%line] %-5level %logger [优先级别:%property{NDC}] ---- %n 【错误信息】 %m%n%n" />
</layout>
</appender>
<root>
<level value="ALL"/>
<appender-ref ref="rollingFile"/>
</root>
</log4net>
