Check whether log4net XmlConfigurator succeeded

Question

How to check whether a call to log4net's XmlConfigurator.Configure succeeded? I want to make a web service call if the logging configuration could not be loaded properly (i.e. file not existent, file not well-formed, etc.)

From the FAQ:

To prevent silent failure of log4net as reported as LOG4NET-342, log4net supports a way to evaluate if it was configured and also to evaluate messages generated on startup since 1.2.11. To check if log4net was started and configured properly one can check the property log4net.Repository.ILoggerRepository.Configured and enumerate the configuration messages as follows:

if(!log4net.LogManager.GetRepository().Configured)
{
  // log4net not configured
  foreach(log4net.Util.LogLog message in log4net.LogManager.GetRepository().ConfigurationMessages.Cast<log4net.Util.LogLog>())
  {
      // evaluate configuration message
  }
}
