concreteclass

After writing a test, I determined that the this pointer in an interface is not equal to the this pointer of the concrete class, meaning I can't just use a C-style cast on it. class AbstractBase {...}; class AnInterface { public: AnInterface() {...} // need AbstractBase * here ~virtual AnInterface() {...} // and here }; class Concrete : public AbstractBase, public AnInterface {}; My interface needs a base class pointer to the concrete class inheriting it in the constructor and destructor in order to handle interface related registration and deregistration. Every concrete object that inherits

I have a list of objects implementing an interface, and a list of that interface: public interface IAM { int ID { get; set; } void Save(); } public class concreteIAM : IAM { public int ID { get; set; } internal void Save(){ //save the object } //other staff for this particular class } public class MyList : List<IAM> { public void Save() { foreach (IAM iam in this) { iam.Save(); } } //other staff for this particular class } The previous code doesn't compile because the compiler requires all the interface members to be public. internal void Save(){ But i don't want to allow the from outside my
