Private Abstract Method C#


So, method overriding is enforced by declaring the method as abstract in the base class named EntityBase. We use virtual or abstract keywords to define a signature for late implementation (to override) for purpose, what benifits if we set its access modifier as private to deny its "offspring" overriding/accessing outside If you use the pattern I showed and you have a lot of derived classes as nested classes then partial classes certainly will help >> > Have you an example of So generally it is discouraged to make virtual methods public, instead internal or protected should be used, so why not allowing private virtual methods? this contact form
