Hi,
I'm having trouble figuring out how to programmatically set the appender for a
logger at run time. I want my logger to be configured by an XML file to obtain
default values but then to dynamically change the appender.
I default my logger to this:
_log =
LogManager.GetLogger("SoeiDental.Logging");//MethodBase.GetCurrentMethod().DeclaringType
XmlConfigurator.Configure();
Where _log is a public static log4net.ILog. Whenever I log, I'm logging using
_log.Warn() or _log.Fata().
My first problem is that I cannot see anyway to access or modify the appender
used by the logger named "SoeiDental.Logging". I've read through the
Configuration chapter of the manual and studied the SDK. Unfortunately the
Configuration chapter seemed very focused on configuration using XML file and
doesn't cover programmatic configuration of a specific logger instance.
Secondly if I resign myself to setting the root logger in this way:
log4net.Appender.FileAppender appender = new
log4net.Appender.FileAppender();
appender.File = path;
appender.AppendToFile = true;
appender.Name = "NewLogFileAppender";
appender.Layout = new log4net.Layout.PatternLayout("%date [%thread]
%-5level %message%newline");
BasicConfigurator.Configure(appender);
It doesn't seem to have any effect. My logging still uses the appender
originally specified in the XML file. The way I understand it
"SoeiDental.Logging" is a child of the root logger and so whenever I log using
this it ought to use all the appenders of its ancestors.
At this stage the only thing I can see to do is to have my code write to the
.config to modify the "File" parameter but this quite twisted way of doing
things, I shouldn't have to write out to file in order to what ought to be
possible with code.
Any help would be greatly appreciated.
Thanks
