I did read that part.
The problem lies more in that I'd like to point to something which is not 
there yet.
In the code 'c.method()' is not there yet, as c is null.
Maybe I should create a dummy object for c to point to in stead of null ?
That way I point the delegate to the dummy method and ignore it as long as 
it is pointing
to the dummy method :)
The only drawback to this is that all objects I want to point the delegate 
to,
need to somehow be convertable to the dummy type (interface/abstract class),
meaning it will be less flexible.
