Editing log4net file value on custom action installer method

Question

Hi there,

I have my log4net configuration in app.config, and I'm trying to change the file key value. I'm trying to use this method:

static bool ChangeLogFileName(string AppenderName, string NewFilename)
    {

        log4net.Repository.ILoggerRepository RootRep;

        RootRep = log4net.LogManager.GetRepository();

        foreach (log4net.Appender.IAppender iApp in RootRep.GetAppenders())
        {

            if (iApp.Name.CompareTo(AppenderName) == 0

            && iApp is log4net.Appender.FileAppender)
            {

                log4net.Appender.FileAppender fApp = (log4net.Appender.FileAppender)iApp;

                fApp.File = NewFilename;

                fApp.ActivateOptions();

                return true; // Appender found and name changed to NewFilename

            }

        }

        return false; // appender not found

    }

But when I try to call this method ( ChangeLogFileName("RollingFileAppender", "C:\Testv2\abc.log") ) there's no Appenders in RootRep, so this returns false.

I have this in the web.config:

<log4net>
 <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="C:\Test\file.log"/>
  <appendToFile value="true"/>
  <datePattern value="yyyyMMdd"/>
  <rollingStyle value="Date"/>
  <staticLogFileName value="true"/>
  <layout type="log4net.Layout.PatternLayout">
   <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
  </layout>
 </appender>
 <root>
  <level value="DEBUG"/>
  <appender-ref ref="RollingFileAppender"/>
 </root>
 <logger name="NHibernate">
  <level value="ERROR"/>
 </logger>
</log4net>
