无论如何要覆盖一个公共虚拟方法或属性，以便它在我的派生类中是私有的吗？

OOps, that just seals it so that you cannot inherit from it again.... I
don''t think that is what your looking for... I''m not sure if you CAN change
the access modifier on it... hmm..
Sorry..

如果你只是在课堂上使用它，那么覆盖它有什么意义
？
为什么不简单地使用该方法的其他名称？

What would be the the point in overriding it
at all if you''ll just be using it inside that class?
Why not simply use another name for that method?
I tried using new on the property and
making it private, but no luck.
如果你是从一个类中派生出来的，那么你必须将
超类中的操作视为契约。不要被侵犯。你可以在超级类的实例上执行的任何操作，你必须能够在
子类的实例上做（Liskov原理）。
因此，你不能让继承的操作比在
超类中更受限制。
一点继承是多态性的可能性，你在
中有些情况下不知道实例是超类还是派生的
类。无论方法是否被覆盖，它仍然必须能够响应超类的操作，
。如果方法被覆盖（例如空方法），则取决于子类
，但它们仍然必须能够响应操作。

If you have derived from a class, you''ll have to see the operations in the
superclass as a "contract" not to be violated. Any operations you can do on
an instance of the superclass, you must be able to do on instances of the
subclasses (Liskov''s principle).
Hence, you cannot make an inherited operation more restricted than in the
superclass.
One point of inheritance is the possibility of polymorphism, where you in
some cases don''t know if the instance is of the superclass or a derived
class. It must still be able to respond to the operations of the superclass,
regardless if the methods are overridden or not. It''s up to the subclasses
if the methods are overridden (with e.g. "empty" methods), but they still
must be able to respond to the operation.
