Question

I’m creating a class named TetraQueue that inherits System.Collections.Generic.Queue class overriding the Dequeue method, here is the code:

public class TetraQueue : Queue<Tetrablock> {    public override Tetrablock Dequeue()    {        return base.Dequeue();    }  } 

But when I try to compile this I get:

Error TetraQueue.Dequeue()’: no suitable method found to override TetraQueue.cs

Thanks in advance.

How do I know if a method is virtual(to avoid this kind of situation)?

Answer 1

Unfortunately the Dequeue method is not virtual so you can’t override it.
