Hi > There is no matching -= for logger.Repository.ConfigurationChanged
There shouldnt be one, becourse once created the instance of the logger will be stored by the repository until aplication ends. I you use the same loggername you will get the same instance. I guess your problem is that you do not use the logmanager or repositorie's GetLogger member but create your instances by yourself (wich will result in multiple instances of logger with the same name). You need to implement the ILoggerFactory interface to create your custom, subclassed logger. Then you configure the Hierarchy to use your factory. ((log4net.Repository.Hierarchy.Hierarchy)log4net.LogManager.GetRepository).LoggerFactory = new CustomFactory(); Now you can use the LogManager or the Repository to create loggers and only one instance per name will be created. hve phn!
