Hi,

There is a method Test() implemented in base class and override in subclass.

In base class itself, how to make sure

this.Test() will just call implementation in base class only?

Thanks a lot!

You can't, that would defeat the purpose of virtual methods. Instead
you can move the base class' implementation of the Test method to
another, not-virtual method (say TestImpl). Call TestImpl from from
Test and call TestImpl directly if you want non-virtual behaviour.

You can not force an implementation in a subclass.

But you can omit the virtual keyword, so they can not
override.
