为什么不能静态类有非静态方法，当非静态类可以有静态方法和变量的变量？

Why can't static classes have non-static methods and variables when non-static classes can have static methods and variables?

什么是具有在非静态类的静态方法和变量的优势在哪里？虽然有一个静态构造函数在非静态类是可以理解的。

What is the advantage of having static methods and variables in a non static class? Though having a static constructor in a non-static class is understandable.

推荐答案

静态类不能被实例摆在首位，因此，即使你可以声明非静态（实例）的成员，他们永远不能被访问。既然是不是真的有一个点，允许它的原因，语言简单地禁止它。

Static classes can't be instantiated in the first place, so even if you could declare non-static (instance) members, they can never be accessed. Since there really isn't a point allowing it for that reason, the language simply prohibits it.

记住，静态类的只是班的，而有两件事情是有直接关系的非静态类：类的自己，实例/对象的类的。

Bear in mind that static classes are just the classes, while there are two things that are directly related to non-static classes: the classes themselves, and the instances/objects of the classes.

一个非静态类可以有静态和非静态成员，以使静态成员适用于类，而非静态成员适用于该类的实例。

A non-static class can have both static and non-static members so that the static members apply to the class, whereas the non-static members apply to the instances of that class.
