Mainly scope and tidyness. Some classes dont really belong anywhere else.

定义有什么好处一个类作为另一个类

Scott，

当嵌套类是外层类的

实现细节时，我会将一个类嵌套在另一个类中。


例如，LinkedList类的Node类。 Node类保存

实际链接。在链表中。


公共类LinkedList


私有类节点

Public Next As Node

Public Previous As Node

公共数据作为对象

结束班级


...


结束类


LinkedList的各种方法，例如Add，创建一个新的Node类，并且

将数据添加到它。 Node类包含之前的&接下来引用

到列表中的其他节点。


希望这有帮助

Jay

Scott,
I will nest one class inside another when the nested class is an
implementation detail of the outer class.

For example, the Node class of a LinkedList class. The Node class holds the
actual "links" in the linked list.

Public Class LinkedList

Private Class Node
Public Next As Node
Public Previous As Node
Public Data As Object
End Class

...

End Class

The various methods of LinkedList, such as Add, creates a new Node class and
adds the data to it. The Node class contains the previous & next references
to the other nodes in the list.

Hope this helps
Jay

"优点"取决于嵌套类的修饰符及其

构造函数。我建议看一下在.NET Framework中使用嵌套类的地方

。

The "advantages" depend on the modifier of the nested class and its
constructor. I suggest to take a look at where nested classes are used
inside the .NET Framework.
