Get the directory of the Log4Net ILog instance

Question

I have a dll, which gets an instance of ILog.

Using this ILog instance, i want to get the directory that the logger is writing to, because I want to create a file with some other info into the same folder.

I tried the following:

var fa = _log.Logger.Repository.GetAppenders().FirstOrDefault(a => a is RollingFileAppender);

For the fileappender, it does not have the fa.File option. The options that it shows me are: .DoAppend(), .Name and .Close()

Any ideas how to get the fa.File value? so that I can derive the directory and create my file in that directory?

Figured it, based on a post here: https://stackoverflow.com/a/1343913/475882

I had to specify the type in <>:

var fa = _log.Logger.Repository.GetAppenders().OfType<RollingFileAppender>().FirstOrDefault();
