    <logger name="BusinessA">

    </logger>  

    <logger name="BusinessB">
      <additivity value="false" />

      <appender-ref ref="RollingFileAppenderB" />
    </logger>  

    <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.");
