C＃：是否有可能返回一个IOrderedEnumerable< T>？ [英] C#: Is it possible to return an IOrderedEnumerable<T>?
问题描述
是否有可能从一个方法中返回一个 IOrderedEnumerable< T> 而不使用 OrderBy 或 OrderByDescending 方法在 IEnumerable< T> ？
不是......但是......也许我错了？
原因：主要是好奇心。这只是一种打我时，使此答案有关返回数字中的数字。而且我的方法会按照给定数字中的权重以升序返回数字。所以我认为如果他们按照框架认可的顺序排列，也可能会很好。当然，我们可以争辩说，从一般的观点来看，它们并没有被订购。但是，是的，如果他们应该或不应该不在这里。只要可能或不可以。
我想我也暗示了一个问题（或者至少现在是）如果 IOrderedEnumerable< T> 不仅仅是一个名字不同的 IEnumerable< T> 。它是否包含更多？我知道它有 ThenBy 和 ThenByDescending 方法，但它们是否使用 IOrderedEnumerable< ; T> ，还是只是直接使用 IEnumerable< T> ？
IOrderedEnumerable< T> > ... 它并不是很难，取决于你需要做什么。最简单的选择就是调用 OrderBy / OrderByDescending ，尽管如此：） 你为什么感兴趣？
Is it possible to return an IOrderedEnumerable<T> from a method without using the OrderBy or OrderByDescending methods on an IEnumerable<T>?
Im guessing perhaps not... but... maybe I am wrong?
Reason: Mostly curiosity. It just kind of hit me when making this answer on returning digits in a number. And my method would return the digits in ascending order, according to their weight in the given number. So I thought it could be nice if they came out ordered in a way that the framework would recognize as ordered as well. Of course we can argue that from a common number point of view they were not ordered. But yeah... if they should or shouldn't wasn't the point here. Just if it was possible or not.
I guess I am also kind of implying a question (or am now at least) on if an IOrderedEnumerable<T> is more than just an IEnumerable<T> with a different name. Does it contain anything more? i know it has the ThenBy and ThenByDescending methods, but do they use anything inside the IOrderedEnumerable<T>, or is it just that they don't make sense to use directly on an IEnumerable<T>?
Well, you can implement IOrderedEnumerable<T> yourself if you want too... it's not hugely hard, depending on what you need to do. The easiest option is just to call OrderBy/OrderByDescending though :)
