asp.net log4net

1. 引用Log4net.dll
2. Global.asax.cs的Application_Start过程中添加如下代码
   

   log4net.Config.DOMConfigurator.Configure();

    

3. web.config配置，在Configuration下添加
   

   <!-- =============== log4net add code =============== -->
       <configSections>
         <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
       </configSections>
       <log4net debug="false">
         <!-- ************以文件方式输出并保存到d:\Application.log.txt************ -->
         <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
           <param name="File" value="C:\Temp\log.txt"/>
           <param name="datePattern" value="MM-dd HH:mm"/>
           <param name="AppendToFile" value="true"/>
           <layout type="log4net.Layout.PatternLayout">
             <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n"/>
           </layout>
         </appender>
         <!-- ************以跟踪方式 Asp.net trace方式查看************ -->
         <appender name="HttpTraceAppender" type="log4net.Appender.ASPNetTraceAppender">
           <layout type="log4net.Layout.PatternLayout">
             <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n"/>
           </layout>
         </appender>
         <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
           <layout type="log4net.Layout.PatternLayout">
             <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n"/>
           </layout>
         </appender>
         <!-- ************以流的方式输出并保存至文本************ -->
         <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
           <!--日志路径-->
           <param name= "File" value= "logs/"/>
           <!--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:2008-08-31.log-->
           <param name= "DatePattern" value= "yyyy-MM-dd&quot;.log&quot;"/>
           <!--日志根据日期滚动-->
           <param name= "RollingStyle" value= "Date"/>
           <layout type="log4net.Layout.PatternLayout">
             <param name="ConversionPattern" value="%date{HH:mm:ss,fff} %-5p-%m%n" />
           </layout>
         </appender>
         
         <root>
           <!--日志级别(OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL)-->
           <level value="all"/>
           <!--所使用的appender节点的name名称-->
           <appender-ref ref="RollingLogFileAppender"/>
         </root>
       </log4net>
       <!-- =============== log4net add end =============== -->

    

4. 在class中引用
   

   private static readonly ILog log = LogManager.GetLogger("RollingLogFileAppender");
   
   log.Info("11111111111111111111");
