    <logger name="BusinessB">

    <root>  
      <level value="INFO" />  
      <!-- 如果你还想为根logger配置appender，可以在这里添加 -->  
    </root>  
  </log4net>  
  
  <!-- ... 其他配置 ... -->  
</configuration>

 

使用：

// 获取BusinessA的logger实例  
ILog logA = LogManager.GetLogger("BusinessA");  
logA.Info("This is a log message for BusinessA.");  
  
// 获取BusinessB的logger实例  
ILog logB = LogManager.GetLogger("BusinessB");  
logB.Info("This is a log message for BusinessB.");
