1) 下载到log4net的dll文件: log4net.dll.

下载好后,你可以将气拷贝到web项目的bin目录,然后给你的web项目加入该文件的reference.

2) 配置log4net.config文件, 代码如下:

<? xml version="1.0" encoding="utf-8"  ?>   
 < log4net  debug ="false" >   
 < appender  name ="LogFileAppender"  type ="log4net.Appender.FileAppender" >   
 < param  name ="File"  value ="Log/MyBlog.log" />   
 < param  name ="datePattern"  value ="YY-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 >   
 < 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 >   
 < appender  name ="RollingLogFileAppender"  type ="log4net.Appender.RollingFileAppender" >   
 < file  value ="log\\MyBlog" />   
 < appendToFile  value ="true" />   
 < rollingStyle  value ="Date" />   
 < datePattern  value ="\_yyyyMMdd'.log'" />   
 < staticLogFileName  value ="false" />   
 < layout  type ="log4net.Layout.PatternLayout" >   
 < conversionPattern  value ="%d \[%t\] %-5p %c - %m%n" />   
 </ layout >   
 </ appender >   
 < root >   
 < level  value ="INFO" />   
    
 < appender-ref  ref ="RollingLogFileAppender" />   
 </ root >   
 </ log4net >

3) 配置Web.Config文件,代码如下:

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][] 代码

< configuration >   
 < configSections >   
 < section  name ="log4net"  type ="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />   
  
...  
  
 < log4net  configSource ="log4net.config" />   
 < system.web >   
  
 </ configuration >

4) 在Global.asax文件中加入如下代码:

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][] 代码

using log4net.Config;

public  class  Global : System.Web.HttpApplication  
\{  
  
 protected  void  Application\_Start( object  sender, EventArgs e)  
\{  
XmlConfigurator.Configure();  
\}  
...  
\}

5) 在客户端类中按如下方法加入日志:

using log4net;

//  将logger作为类的成员变量   
 private  static  readonly  ILog logger  =  LogManager.GetLogger( typeof (类名));  
  
...  
  
logger.Info( " 信息日志 " );  
  
logger.Error( " 错误日志 " );
