推荐答案

我建​​议您购买一本基本的OO书并阅读.我看不到如何在论坛回复中进行介绍.

例如，如果您所需的只是该类的单个属性，则将对象传递给方法可能是懒惰的.例如，将类的表示存储到数据库中的方法也很有意义.类只是一个对象，它与内置类型(例如int和string)的等级相同.如果需要使用某种方法来处理它，则将其传递给它.如果在类中生成它，则将其返回.确实没有比这更复杂.

I suggest you buy a basic OO book and read it. I don''t see how I can cover this in a forum reply.

Passing an object into a method can be lazy, for example, if all you need is a single property off that class. It can also make sense, for example, a method that stores a representation of the class into the database. A class is just an object, it has equal ranking to the types that are built in, such as int and string. You pass it in if you need to work on it in a method. You return it, if you generate it in the class. It''s really not more complex than that.
