C ＃中的其中一种语言：它的目的是为了成为一个真正面向对象，基于组件的语言。因此，要获得绝对最大的这本书，你需要有一个强有力的概念把握这里提出.-The goals of this chapter are to guide you through the terminology of object-oriented programming (OOP) and to give you an understanding of the importance of object-oriented concepts to programming. Many languages, such as C++ and Microsoft Visual Basic, are said to " support objects,"　but few languages actually support all the principles that constitute object-oriented programming. C# is one of these languages: it was designed from the ground up to be a truly object-oriented, component-based language. So, to get the absolute maximum out of this book, you need to have a strong grasp of the concepts presented here.
