Interface reimplementation
-
Suppose ...
public interface IMyInterface{ void MyMethod(); } public class ClassA:IMyInterface{ public void MyMethod(){} } public class ClassB:ClassA,IMyInterface{ public void MyMethod(){} }Can anyone tell me if it's required to specify that ClassB inherits IMyInterface ? The interface is to my opinion inherited through the base class ClassA, but it seems specifying (or not) the interface inheritance in the derived class ClassB makes no difference. -

This normally means you have designed something wrong :) To override the interface implementation, you would likely have to use an explicit implementation.

Indeed I want to override (reimplement) the interface behaviour in the derived ClassB, but my question really is wether to use ...
public class ClassB:ClassA,IMyInterfaceorpublic class ClassB:ClassAas the ClassB declaration ? Both work for me, but I was wondering if there's a difference (behind the scenes ?) for either one of them !
