Ross, Thanks for the help, greatly appreciated.
We are in the process of porting the application from one platform (Java) to .NET and on the Java platform we have the ability to control all aspects of the log message. Thus I was expecting to be able to replicate the message format in .NET so that it came out the same way. Understanding the log4net is a port I am not surprised to see minor differences in the implementations, but am a little surprise to see the different behaviour between the two different types of loggers. Thanks for the insight.

Apparently, log4net sets the category of the debug message to the logger name. You can try it for yourself: logger.Debug("hello!"); Debug.WriteLine("hello!",logger.Logger.Name); .... should produce the same output. This is actually by design, per the documentation: http://logging.apache.org/log4net/release/sdk/log4net.Appender.DebugAppender.html So, back to your original question before I totally understood the problem: yes, you can control this, but you'll have to set up another logger. You could do something like this: <logger name=""> <appender-ref ref="DebugAppender"/> </logger> ...and then use log4net.LogManager.GetLogger(string.Empty); ...to accomplish what you're trying to do, at least for development. You should not leave it that way for production. In fact, I'd recommend naming the logger something meaningful (although shorter than your namespace) and using that. -Ross On Tue, May 11, 2010 at 12:44 PM, Steven Whatmore <steven.whatm...@purefacts.com> wrote: First, thanks for the assistance.

How are you retrieving the logger from the log manager? If you're using it by type, and are using the root logger, I believe the log name defaults to the namespace of your binary. -Ross On Tue, May 11, 2010 at 12:17 PM, Steven Whatmore <steven.whatm...@purefacts.com> wrote: That is what I thought - but no luck with that - I can't remember which class I was looking at but it sure looks like you can't control that prefix value - which I thought was very strange From: Ross Hinkley [mailto:rosshink...@gmail.com] Sent: Tuesday, May 11, 2010 1:07 PM To: Log4NET User Subject: Re: Controlling the log message format This should be controllable via the conversionPattern.

Am I correct? Whatty
