Rolling Logs in log4net or log4j?

We need to configure log4net to create a new log file each time our Windows Forms application starts.  It seems like the RollingFileAppender should handle this, but I can't find an example that does this.  The examples I find are all the same, keeping 10 logs of up to 100k each.  Is there a way to configure log4net to create a new file each time the  application starts, keeping the most recent 3?  I'd also like to name the log files based on the start time.

We're using log4net 1.20-beta 8, which is a port of log4j, so if you know how to do it in either one, I'd like to hear about it.

Thanks,
Ted

log4j has a DailyRollingFileAppender.  Has it not been ported to log4net, yet?

You could look at the DailyRollingFileAppender code and "roll" your own ;-)

Did you have any problem getting log4net working initally? I have spent a little time trying to get it working in a Windows Forms application, so far without luck. Did you use the 1.1 binary that comes with the beta 8 release?

When I tried using it in the mode that looks for a config file with the same name as the exe + config, it deleted my config file at startup. Running the console sample app works fine.

Was there any gotcha that you overcame to get it working?

Hi ICBW:

No problems on getting it to work with Windows Forms, but this is my third app to use log4net, so I may have had something tricky I setup 2 years ago when I started using it that I have forgotten.  My log4net.dll is version 1.2.0.30714.

Hoo boy. After KayJay's post about complex numbers and 3 dimensional spaces I though this would be something about logarithms and Microsoft's .Net solution to the 4th dimension. Moving on now...

Hmmm. I'll try it again on Sunday.
