Question

I have been doing what it was suggested in Best way to dynamically set an appender file path to set the file name dynamically, using %property{}, but the file is created as “(nul).log” below is the code

log4net.GlobalContext.Properties["service"] = _servicename.ToString();
_flatFileLogger = LogManager.GetLogger("FlatFileLogger");
_flatFileLogger.Debug(logData.ToString());

I have declared in the XML file as

file type="log4net.Util.PatternString" value="C:\My_Log\%property{service}.log"

Help much appreciated.

Make sure you’re setting the property before you initialize log4net.
