What would be the best way to change the path of the log file at run time?

  you can change the filepath at runtime


           Configuration config = ConfigurationManager.OpenExeConfiguration(System.Configuration.ConfigurationUserLevel.None);
           LoggingSettings loggingSettings = (LoggingSettings)config.GetSection(LoggingSettings.SectionName);
           FlatFileTraceListenerData flatfiletracedata = loggingSettings.TraceListeners.Get("FlatFile TraceListener") as FlatFileTraceListenerData;
           flatfiletracedata .Filename = {your new filepath}

once you start logging to  a file ....the file will be locked as the log file until application restart

Thanks for you reply. Is there something else I need to do? That code does in fact change the FileName property but the logs are still being written to same location.

once you have made your changes in the constructor you need to add


this will write the new file path into your actual config file.
