静态类在C＃ [英] Static classes in c#

问题描述

在回答这个问题（ http://stackoverflow.com/questions/352317/c-coding-问题＃352327 ），它让我知道...

In answering this question (http://stackoverflow.com/questions/352317/c-coding-question#352327), it got me wondering...

有没有关于一个静态类等价于一个非静态类instatiation任何危险实现Singleton模式？

Is there any danger in regarding a static class as being equivalent to a non-static class instatiation that implements the singleton pattern?

推荐答案

这似乎是显而易见的，以我的唯一的事情就是一个静态类，基本上是一个集合的范围功能（避免明确办法在这里）和一个单身还是东西，你可以实例，即使你只能有1 1> 0

The only thing that seems immediately apparent to me is that a static class is basically just a collection of scoped functions (explicitly avoiding "methods" here) and a singleton is still something you can instantiate, even if you can only have 1. 1 > 0.

您可以通过一个单身作为一个参数的东西，希望某个接口的对象，就可以不通过静态类的任何地方（除了通过一些反射挂羊头卖狗肉）

You can pass a singleton as an argument to something that expects an object of a certain interface, you cannot pass a static class anywhere (except through some reflection trickery)
