匿名类型可以从另一个类型继承？ [英] Can an anonymous type inherit from another type?

问题描述

根据对<一个MSDN文档href="http://msdn.microsoft.com/en-us/library/system.stringcomparer.ordinalignorecase.aspx"><$c$c>StringComparer.OrdinalIgnoreCase属性：

在OrdinalIgnoreCase属性返回从 StringComparer 类。

The OrdinalIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

这是一个功能，我不熟悉，匿名类型继承？或者通过匿名类也撰文只是意味着内部类派生从 StringComparer ，不可见的客户端code？

Is this a feature I'm unfamiliar with—anonymous types with inheritance? Or by "anonymous class" did the author simply mean "internal class deriving from StringComparer, not visible to client code"?

推荐答案

如果你看一下源$ C ​​$下StringComparer，你可以看到，OrginalIgnoreCase返回OrdinalComparer，这是从StringComparer派生的一个实例。

If you look at the source code for StringComparer, you can see that OrginalIgnoreCase returns an instance of OrdinalComparer, which is derived from StringComparer.

没有什么匿名关于这个，我可以看到，它只是它的的内部的，所以你不能从框架之外看到它。

There's nothing 'anonymous' about this that I can see, it's just that it's internal so you can't see it from outside the framework.
