Implementing interface & redefining a method.

Morning,

public interface MyInterface{
	int Calculate();
}
public class MyClass:MyInterface{
	int Calculate(){return 0;}
	int Calculate(){return 1;}
}

Open in new window

Obviously the above code is very wrong as Calculate is defined twice within MyClass, but is there a way I can state that one of the Calculate methods only be accessible through MyInterface and the other Calculate method available through MyClass. So:

void Test(){
	
	MyClass a=new MyClass();
	a.Calculate();	//Returns 0

	MyInterface b=(MyInterface)a;
	b.Calculate();	//Returns 1
}

Open in new window

Any tricks to make this possible without having two different named methods?

Thank you,
Uni

Oh of course! :)And using the new (well, perhaps not so new now) default arguments...

public interface MyInterface{
	int Calculate(bool aIgnore=true);
}

public class MyClass:MyInterface{

	int Calculate(){
		return 0;
	}

	int Calculate(bool aIgnore=true){
		return 1;
	}

}

void Test(){
	
	MyClass a=new MyClass();
	a.Calculate();	//Returns 0

	MyInterface b=(MyInterface)a;
	b.Calculate();	//Returns 1
}

Open in new window

That should suffice, yes?

Thanks,
