推荐答案

根据我的喜好，
.
C#是一种面向对象的语言，所有内容都是基于类的.它没有要描述的全局"变量的概念.但是，在某些情况下，最好使用单个应用程序范围的变量-例如，可以从配置文件中读取一次到数据库的连接字符串，并将其存储在静态变量中.像这样的案例非常非常少-否则您的设计有一些错误.

发生这种情况时，我通常会构造一个静态类，并使用该类包含静态变量，以及任何与类无关的方法(这种方法同样很少见).

By preference, I don''t.
C# is a object oriented language, and everything is class based. It has no concept of "global" variables, which is what you are describing. However, there are occasions when a single application-wide variable is a good idea - the connection string to a database for example, could be read from a config file once, and stored in a static variable. Cases like this are very, very rare though - or there is something very wrong with your design.

When that happens, I generally construct a static class, and use that to contain the static variable, along with any non-class related methods (which again are as rare as possible).
