I have chosen to use:

    public InterfaceImpl(Type type) : base (log4net.LogManager.GetLogger(type).Logger) { }
 
    IInterface _logger = new InterfaceImpl(typeof(MyClass));

...this makes a lot of sense and it works!

The cleanest way of doing this would be to implement your own LogManager. However if you really don't want to do that and want to just have your IInterface and InterfaceImpl, the best way I see would be to make sure your InterfaceImpl constructor is public and use log4net's LogManager to get an ILog, and use its ILogger to initialize your InterfaceImpl:
 
    IInterface _logger = new InterfaceImpl(log4net.LogManager(typeof(MyClass)).Logger);
 
A cleaner way would be to add a new constructor to your InterfaceImpl:
 
    public InterfaceImpl(Type type) : base (log4net.LogManager.GetLogger(type).Logger) { }
 
so that you can do this:
 
    IInterface _logger = new InterfaceImpl(typeof(MyClass));

Subject: Building A Custom Logger

Has anyone had experience building a custom logger?

Here is what I am doing. I have created my own interface describing what the kinds of things a logger needs to be able to log in my environment (let's call it IInterface) like security audits, performance statistics, etc. This interface extends ILog as well.
Thus: IInterface : ILog

Then, I have an implementation of IInterface and we'll call that InterfaceImpl which also inherits from LogImpl (in order to satisfy the ILog interface).
Like so: InterfaceImpl : LogImpl, IInterface

Now, when I go to put a logger in a class in which I want to perform logging, by default I would usually put the line of code:
ILog _logger = LogManager.GetLogger(typeof(MyClass));

What I would like to do is to be able to say:
IInterface _logger = LogManager.GetLogger(typeof(MyClass));

...but this does not work (nor does anything else I have tried) because GetLogger returns LogImpl which knows nothing of my IInterface.

Can anyone recommend anything that I can try without needing to modify the LogManager (a sealed class)?
