c# - How to add log4net appender in runtime?

How do I add an extra log appender in runtime? (all pre-existing appenders must keep on working)
I'm trying it this way:

        var layout = new PatternLayout("%utcdate %-5level - %message%newline");
        layout.ActivateOptions();
        _log4netAppender = new FileAppender
            {
                Layout = layout,
                File = logFilePath,
            };
        _log4netAppender.ActivateOptions();
        BasicConfigurator.Configure(_log4netAppender);

but it doesn't write anything to the file.

You should also add the appender to a logger. Take a look here Adding Appenders programmatically

If the logger you are using is, for example ILog logger do:

((log4net.Repository.Hierarchy.Logger)logger.Logger).AddAppender(appender)
