Using parent class logger in child class

Question

I have a base class for all controllers and the logger is defined there:

public abstract class BaseService
{
    private static readonly ILogger logger = LogManager.GetCurrentClassLogger();

    protected ILogger Logger => logger;
}

public class ChildClass : BaseClass 
{
    public void DoStuff() 
    {
        Logger.Info("Some info");
    }
}

Now when I use Logger from a child class, the log entry shows BaseService as logger. Is there a way to tell the log manager to instantiate the logger for the child class?

Answer 1

Here is how you can do it:

public abstract class BaseService
{
    protected ILogger Logger => LogManager.GetLogger(this.GetType().FullName);
}

Please note that GetLogger caches the logger internally (for each different name) so that you don't create a new logger every time the Logger property is obtained.

The trick here is that this.GetType().FullName will return the name of the derived type, not BaseService.
