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.
