Log4Net: Multiple loggers

问题

I have the following log4net configuration:

<log4net>
  <appender name="A1" type="log4net.Appender.RollingFileAppender">
    <file type="log4net.Util.PatternString" value="C:\path1.log" />
  </appender>

  <appender name="A2" type="log4net.Appender.RollingFileAppender">
    <file type="log4net.Util.PatternString" value="C:\path2.log" />
  </appender>

  <logger name="A1Logger">
    <level value="ALL" />
    <appender-ref ref="A1" />
  </logger>

  <logger name="A2Logger">
    <level value="ALL" />
    <appender-ref ref="A2" />
  </logger>

</log4net>

and then in code I do the following:

var logger1 = LogManager.GetLogger("A1Logger");
var logger2 = LogManager.GetLogger("A2Logger");

but both log to the same file C:\path1.log.

What am I doing wrong?

回答1:

Add the debug="true" attribute to the <log4net> element, my guess is that it is the missing <root> element that causes problems. You should always include the <root /> logger element.

回答2:

Seems that it was a weird debugging error. Right now it doesn't reproduce. My apologies.
