RE: Changing FileAppender log file at runtime

[corey . wirun]

Thanks for the code snippet, Barry!

So I assume I take the existing FileAppender <appender> configuration out of
my configuration file.  A small wrinkle though: I've got a TraceAppender
defined in the config file right now - I can leave that as is and both
appenders will still work?  Or does the
log4net.Config.BasicConfigurator.Configure bypass any config file?

Thanks again.
Corey.

Here is the code to do exactly what you want:

Hierarchy hierarchy;

if((hierarchy = (Hierarchy)
LogManager.GetLoggerRepository()) != null ) {
    FileAppender  fileAppender          = new FileAppender();

    PatternLayout patternLayout         = new
PatternLayout();

    string                logFile       = string.Format(
@"{0}\myLogFile.log", myLogDir );
    string                logThreshold  = "DEBUG"; // whatever you
want here...

    patternLayout.Header                = "[Begin]\r\n";
    patternLayout.Footer                = "[End]\r\n\r\n";
    patternLayout.ConversionPattern     = "%d [%t] %-5p
%c - %m%n";

    fileAppender.Name                   = config.myAppenderName;
    fileAppender.File                   = logFile;
    fileAppender.AppendToFile           = true;
    fileAppender.ImmediateFlush         = true; // IMPORTANT
    fileAppender.Layout                 = patternLayout;
    fileAppender.Threshold              = Level.DEBUG;

    fileAppender.ActivateOptions();

    log4net.Config.BasicConfigurator.Configure(
fileAppender );
}
