Thanks for proposal to John and Ron, it works well.
But when I tried the reverse strategy (set Threshold to OFF in config file and 
change to DEBUG when needed), I noticed that empty log file (Service.log in my 
configuration) is created (file size = 0 bytes).
Can this feature be disabled?

I think it would be great to add some samples of programatic configuration into 
SDK documentation - current documentation is completely out of any example.

Instead of removing the appender you could just set its threshold to OFF then 
when you want to enable it again you can set it back to DEBUG:

// untested
public static void SetThreshold(string appenderName, Level threshold)
{
foreach (AppenderSkeleton appender in 
LogManager.GetRepository().GetAppenders())
{
if (appender.Name == appenderName)
{
appender.Threshold = threshold;
appender.ActivateOptions();
break;
}
}
}

Subject: Disable/enable appender for all loggers



Disable/enable appender for all loggers Hello, 

I am using three appenders in my log4net configuration (see bellow). But I need 
programatically disable and reenable RollingFile appender at certain 
situations. Is there any simple solution? I tried to use programatic 
configuration only.

My config: 

<log4net> 

<appender name="Console" 
type="log4net.Appender.ConsoleAppender"> 

<layout type="log4net.Layout.PatternLayout"> 

<!-- Pattern to output the caller's file name 
and line number --> 

<conversionPattern value="%date{HH:mm:ss,fff} 
%5level [%thread] %message%n" /> 

</layout> 

<Threshold value="DEBUG" /> 

</appender>

<appender name="RollingFile" 
type="log4net.Appender.RollingFileAppender"> 

<appendToFile value="true" /> 

<file value="Service.log" /> 

<layout type="log4net.Layout.PatternLayout"> 

<conversionPattern value="%date{dd-MM-yyyy 
HH:mm:ss,fff} %5level [%2thread] %message (%logger{1}:%line)%n" />

</layout> 

<rollingStyle value="Date" /> 

<Threshold value="DEBUG" /> 

</appender>

<appender name="EvLog" 
type="log4net.Appender.EventLogAppender"> 

<ApplicationName value="IPserver" /> 

<layout type="log4net.Layout.PatternLayout"> 

<conversionPattern value="[%thread] %message 
(%logger{1})" /> 

</layout> 

<Threshold value="INFO" /> 

</appender>

<root> 

<level value="DEBUG" /> 

<appender-ref ref="RollingFile" /> 

<appender-ref ref="Console" /> 

<appender-ref ref="EvLog" /> 

</root> 

</log4net>

I tried to complete rewrite this config into C# code:

private readonly log4net.Appender.ConsoleAppender AppConsole; 

private readonly log4net.Appender.RollingFileAppender AppFile; 

private readonly log4net.Appender.EventLogAppender AppEvlog; 

private log4net.Repository.Hierarchy.RootLogger rootLog; 

//XmlConfigurator.Configure(new 
System.IO.FileInfo(IPserverCore.IPserver.GetAppPath() + "log4net.config")); 

//xml configurator replaced by code 

AppConsole = new log4net.Appender.ConsoleAppender(); 

AppConsole.Layout = new log4net.Layout.PatternLayout("%date{HH:mm:ss,fff} 
%5level [%thread] %message%n"); 

AppConsole.Threshold = log4net.Core.Level.Debug;

AppFile = new log4net.Appender.RollingFileAppender(); 

AppFile.AppendToFile = true; 

AppFile.Layout = new log4net.Layout.PatternLayout("%date{dd-MM-yyyy 
HH:mm:ss,fff} %5level [%2thread] %message (%logger{1}:%line)%n");

AppFile.File = "Service.log"; 

AppFile.RollingStyle = log4net.Appender.RollingFileAppender.RollingMode.Date; 

AppFile.Threshold = log4net.Core.Level.Debug;

AppEvlog = new log4net.Appender.EventLogAppender(); 

AppEvlog.Layout = new log4net.Layout.PatternLayout("[%thread] %message 
(%logger{1})"); 

AppEvlog.ApplicationName = "IPserver"; 

AppEvlog.Threshold = log4net.Core.Level.Info;

rootLog = new 
log4net.Repository.Hierarchy.RootLogger(log4net.Core.Level.Info); 



rootLog.AddAppender(AppConsole); 

rootLog.AddAppender(AppFile); 

rootLog.AddAppender(AppEvlog); 

//---- 

log = LogManager.GetLogger(typeof(IPservice)); 

Log.Info("Start"); // no log produced here... 

rootLog.RemoveAppender(AppFile); // disable file logging 

... 

But after rewriting aplication doesn't create any logs.... 

Did I miss some settings or am I complete wrong?

Thanks for any suggestions
