什么你想通过指定这个关键字来实现它吗？！

它可能在嵌套类的上下文中有意义。我已经完成了几次

。

关键字。 "朋友"和公共是唯一两个范围修饰符，可以

受保护意味着该类仅在外部类中可见且
$ b来自外部类的$ b类。


class outerclass

受保护的MustInherit类MyBaseClass

...

...

结束类

结束类

如果没有外部类，因为你将MyBaseClass放在命名空间中，

受保护无效且没有意义。

What do you want to archieve by specifying this keyword?!

It could make sense in the context of nested classes. I''ve done that a
few times.

To the original poster: Most likely you are looking for the "Friend"
keyword. "Friend" and "Public" are the only two scope modifiers that can
apply to top-level classes.

Protected means that the class is only visible in the outer class and the
classes derived from the outer class.

class outerclass
Protected MustInherit Class MyBaseClass
...
...
End Class
end class
If there is no outer class because you put MyBaseClass in a Namespace,
protected is invalid and doesn''t make sense.
