Determine which class or assembly instantiated an object with Castle Windsor container

Question

I use the newest Castle Windsor container and I would like to create a logger, which will write to file what I want but also write the caller assembly name. So here is an example:

namespace Core.Datalayer
{
    public class Foo
    {
       public Foo(ILogger logger)
       {
          logger.Write("test line");
       }
    }
}

The container gives the instance correctly, but I cannot figure out how can I determine the Caller assembly name or the Caller class name? I would like that the logger writing to file something like this:

"assembly Core.Datalayer- test line"

Is there any possibility to determine that where instantiated the ILogger interface?

I tried the Assembly.GetCallingAssembly() but is always Castle.Core because the stack is full with Castle.Core calls.

Which logging framework are you using? log4net, nlog, something else? — Patrick Quirk, Aug 27 '14 at 19:16
I don't use any framework for logging it is just a simple logger. I write the text in file directly. — Vajda Endre, Aug 27 '14 at 19:18

This or similar functionality is built into most major logging frameworks. I'd really recommend using one! — Patrick Quirk, Aug 27 '14 at 19:44
I agree using a logging framework is far simpler and better. Still I've tried to answer how to do this with Windsor. — Marwijn, Aug 28 '14 at 06:26

You can use a subdependency resolver. I think something like the code below should work for you.

public class Logger
{
    public Logger(string name)
    {
    }
}

public class LogResolver : ISubDependencyResolver
{
    public bool CanResolve(CreationContext context, ISubDependencyResolver contextHandlerResolver, ComponentModel model,
                           DependencyModel dependency)
    {
        return dependency.TargetType == typeof(Logger);
    }

    public object Resolve(CreationContext context, ISubDependencyResolver contextHandlerResolver, ComponentModel model,
                          DependencyModel dependency)
    {
        return new Logger(model.Name);
    }
}

install the logger int the container with

container.Kernel.Resolver.AddSubResolver(new LogResolver());

Thanks a lot! I struggled with it nearly one day. That's what I want! :) — Vajda Endre, Aug 28 '14 at 07:02
