您的问题的第二版与第一版完全不同。



我是建议您阅读：继承和派生类 [< a href =http://msdn.microsoft.com/en-us/library/ms228387%28v=vs.90%29.aspxtarget =_ blanktitle =New Window> ^ ] 。

The second edition of your question totally differs from first one.

I'd suggest you to read this: Inheritance and Derived Classes[^].

Quote：

要覆盖的基本方法必须声明为虚拟，抽象或覆盖：无法以这种方式覆盖非虚拟或静态方法。

The base method, which is to be overridden, must be declared as virtual, abstract, or override: it is not possible to override a non-virtual or static method in this way.
