推荐答案

通常，我们不调用变量.但是，粗略地说，是的，实际上，我们可以访问(公共)静态变量而无需创建其类的实例.
静态成员应包含类属性，即类的所有实例共享的数据(如果没有创建对象，则所有都是).

Usually we don''t call a variable. However, roughly speaking, yes, actually we can access a (public) static variable without creating an instance of its class.
static members should contain class attributes, that is data shared by all the instances of the class (none is all when no object is created).

CPalini的回答是，C#定义了七类变量，其中包括静态变量.
在这里看看:
变量类别(C#) [静态变量(C#) [静态(C#参考) [

In addition of CPalini''s answer, C# defines seven categories of variables, among other things, static variables.
Have a look here:
Variable categories (C#)[^]
Static variables (C#)[^]

But i think, you want to know about static modifier (keyword). If yes, see here:
static (C# Reference)[^]

Use the static modifier to declare a static member, which belongs to the type itself rather than to a specific object. The static modifier can be used with classes, fields, methods, properties, operators, events, and constructors, but it cannot be used with indexers, destructors, or types other than classes.

静态变量还可以提高性能，因为它们将存储存储到一个单独的堆中，该堆与Garbage Collector堆(称为高频堆")分开.请参考静态关键字已神秘化 [

Static variables are also improving performance as they are getting stores into a separate heap, a separate heap from Garbage Collector heap, which is referring as "high frequency heap". Refer Static Keyword Demystified[^].

Also variables can be defined without taking additional memory.

Static variables resolved good designing changeless like Singleton implementation.

Just Google it you will get lot more information about it.
