Here's another way of storing extra information with the logging event:
// untested
public void Info(object message, Exception ex, object additional)
{
if (Logger.IsEnabledFor(Level.Info))
{
LoggingEvent loggingEvent = new LoggingEvent(
declaringType,
Logger.Repository,
Logger.Name,
Level.Info,
message,
ex);
loggingEvent.Properties["additional"] = additional;
Logger.Log(loggingEvent);
}
}

If the call looks like this:
log.Info("Oh no!", ex, 1234);
I can access 1234 by using the property pattern:
<conversionPattern value="%property{additional}" />
(4)
If you configure log4net using the ConfigureAndWatch method:
XmlConfigurator.ConfigureAndWatch(
new FileInfo(
AppDomain.CurrentDomain.SetupInformation.ApplicationBase +
"log4net.config"));
log4net will attempt to reload itself when the configuration file
changes.
