RE: Programmatically setting the logger level

Kevin,

Only the BufferingAppenderSkeleton classes support the Evaluator (i.e. the
ADONetAppender, BufferingForwardingAppender, RemotingAppender, SMTPAppender
and SmtpPickupDirAppender appenders).

If what you want is to set the event threshold for the appender then you do
not need to use the Evaluator at all. i.e. the following configuration would
work:

<appender>
  <param name="Threshold" value="WARN" />
</appender>

Or the equivalent:

<appender>
  <threshold value="WARN" />
</appender>

To set this in code you would use:

fileAppender.Threshold =
log4net.LogManager.GetLoggerRepository().LevelMap["WARN"];

Hope this helps,

Nicko
