The current implementation of LogManager.GetLogger returns
log4net.Core.LogImpl. In its constructor, LogImpl queries its repository and
stores the current level mappings. The LogImpl isn't aware of LevelMap changes
after its been created. Maybe changing a repository's LevelMap should trigger
the ConfigurationChanged event. It may be possible to make your own LogImpl
that always looks up Level values from the repository.
On a related note, I can't figure out why this is failing:
StringAppender stringAppender = new StringAppender();
stringAppender.Layout = new PatternLayout("%message");
string repositoryId = Guid.NewGuid().ToString();
ILoggerRepository repository = LogManager.CreateRepository(repositoryId);
repository.LevelMap.Add(Level.Warn.Name, Level.Off.Value);
BasicConfigurator.Configure(repository, stringAppender);
ILog log = LogManager.GetLogger(repositoryId, "TestFormatString");
log.Warn("Warn acting as Off. This message should not appear.");
Assert.IsEmpty(stringAppender.GetString());
One option is to add a Filter to all of your appenders that checks for a
property in the repository then aborts the logging call if necessary:
log.Logger.Repository.Properties["DEBUG-DISABLED"] = true;
foo();
log.Logger.Repository.Properties.Remove("DEBUG-DISABLED");
There may be other options if I can figure out why my test code is failing.

Below is the structure of my code. In my constructor, I load my configuration
file and configure my log4net logger.
myFunction() method gets called from the Main() method. As you can see, when
entering the myFunction() method, I want to set the log level to OFF and then
reset it to DEBUG while exiting the function. The myFunction() methods calls
several other components and methods (for eg: a,b, c, etc) to do stuff and
hence passing the Boolean variable to this method will not work. Also, having
an separate appender will not work in my scenario, since the methods a, b and c
will be used in various other places as well.
public myConstructor()
{
if (logconfigpath == null)
{
logconfigpath =
System.AppDomain.CurrentDomain.BaseDirectory;
logconfigpath +=
System.AppDomain.CurrentDomain.RelativeSearchPath;
log4net.Config.XmlConfigurator.Configure(new
System.IO.FileInfo(Path.GetFullPath(logconfigpath) +
Path.DirectorySeparatorChar.ToString() + "myconfigfile.xml"));
}
}
public void Main(XmlElement oParameter1, string sParameter2, string
sParameter3, string sParameter4)
{
logger.Info(System.Reflection.MethodBase.GetCurrentMethod() + ":
Entering.");
//do my stuff here.
String sResult = myFunction (oParameter1, sParameter2);
logger.Info(System.Reflection.MethodBase.GetCurrentMethod() + ":
Leaving.");
}
private string myFunction(XmlElement oParameter1, string sParameter2)
{
//turn off logging here...I would like to set the loglevel to OFF
//do my stuff here.
//turn on the logging .....I would like to reset the loglevel to DEBUG
}
After looking around on the internet, I found this code
log4net.Repository.Hierarchy.Logger logger2 =
(log4net.Repository.Hierarchy.Logger)log4net.LogManager.GetLogger("myappendername").Logger);
logger2.Level = logger2.Repository.LevelMap["OFF"];
But this is not working as expected. Log messages are still being writing to
my log file, even though the level is set to OFF. Obviously, I'm missing
something here.
Please help
Thank you

Is it possible to turn off the logging for a specific event? I would like
to turn of the logging when the code hits a particular method and reset the
logging to its original value which is "DEBUG" while exiting that method. Is it
possible to accomplish this? If so, please provide me some sample code on how
to achieve this. My code is in c#.net and uses log4net version 1.2.10
Please help
Thanks.
