Dear all,
For lonmg time now I try to understand clearly the sue of
intervface in .NET by many example and articles,and
comments from different source. But seems that each of us
has they own ideas of interface outside from the fact of
the basic rules of polymorphisme.
For me Interface means a kind of FierWall between a class
user and the class provider. such like properties and
methods. When property and methosde are implemented in a
class it is really clear that from outside we just see
those interface and we do not care about how it works as
long as we provide correct parameters.
Now the confusion comes when we introduce the notion of
Interface implementation. If each class when implementing
an interface need to define its own way of handling the
methode or property , they is not anymore this kind of
Firewall compare to simmple class interface.
What the system really do when is managing methode trhough
interface compare to class property or methode.
Does anyone can clarify my ideas of interface use and when
to use, is there any rules...
I know thats hard to explain but lets try
Thanks for your help
Regards
serge
