RE: File logging

[Nicko Cadell <ni...@neoworks.com>]

In log4net 1.2.9 beta you can do the following to set the File property
on a configured appender:

foreach(log4net.Appender.IAppender appender in
log4net.LogManager.GetRepository().GetAppenders())
{
  if (appender is log4net.Appender.FileAppender)
  {
    ((log4net.Appender.FileAppender)appender).File = "path";
    ((log4net.Appender.FileAppender)appender).ActivateOptions();
  }
}

If you have more than 1 FileAppender you may want to check the appenders
Name property.

If you are using an older version of log4net without the GetAppenders
method you will need to do this manually:

public static log4net.Appender.IAppender[] GetAppenders()
{
  ArrayList appenders = new ArrayList();

 
appenders.AddRange(((log4net.Repository.Hierarchy.Hierarchy)log4net.LogM
anager.GetLoggerRepository()).Root.Appenders);
  foreach(log4net.ILog log in log4net.LogManager.GetCurrentLoggers())
  {
 
appenders.AddRange(((log4net.Repository.Hierarchy.Logger)log.Logger).App
enders);
  }

  return
(log4net.Appender.IAppender[])appenders.ToArray(typeof(log4net.Appender.
IAppender));
}
