在.Net程序中使用log4net记录日志(示例)

log4j是java开发人员所熟悉，他提供了强大的日志记录功能，log4net是为.net记录日志开发的.使用示例如下(c#)：
1、app.config文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <appsettings>
  <add key="log4net-config-file" value="log4net.config"/>
 </appsettings> 
</configuration>
2、log4net.config文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- this section contains the log4net configuration settings -->
 <log4net>
  <!-- define some output appenders -->
  <appender name="rollinglogfileappender" type="log4net.appender.rollingfileappender">
   <param name="file" value="log\\lqss-ss-log.txt" />
   <param name="appendtofile" value="true" />
   <param name="maxsizerollbackups" value="10" />
   <param name="maximumfilesize" value="100kb" />
   <param name="rollingstyle" value="size" />
   <param name="staticlogfilename" value="true" />
   <layout type="log4net.layout.patternlayout">
    <param name="header" value="[header]\r\n" />
    <param name="footer" value="[footer]\r\n" />
    <param name="conversionpattern" value="%d [%t] %-5p %c [%x] - %m%n" />
   </layout>
  </appender>  
  <appender name="consoleappender" type="log4net.appender.consoleappender">
   <layout type="log4net.layout.patternlayout">
    <param name="conversionpattern" value="%d [%t] %-5p %c [%x] &lt;%x{auth}&gt; - %m%n" />
   </layout>
  </appender>
  <!-- setup the root category, add the appenders and set the default level -->
  <root>
   <level value="info" />
   <appender-ref ref="rollinglogfileappender" />
  </root>
  <root>
   <level value="debug" />
   <appender-ref ref="consoleappender" />
  </root>
 </log4net>
</configuration>
3、代码文件
using log4net;
using log4net.config;
class program
 {
  private static ilog logger = logmanager.getlogger(system.reflection.methodbase.getcurrentmethod().declaringtype);
  
  /// <summary>
  /// 应用程序的主入口点。
  /// </summary>
  [stathread]
  static void main(string[] args)
  {
   try
   {
    domconfigurator.configure(
                                    new fileinfo(configurationsettings.appsettings["log4net-config-file"]));    
    logger.info("start application...");
    console.writeline(“请按 <enter> 键退出...");
    system.console.readline();
   }
   catch (exception e)
   {
    logger.info (e);
   }
  }
 }
