This wraps up our brisk overview of the pillars of OOP. Now that you have the theory in your

mind, the remainder of this chapter explores further details of how encapsulation is handled under

C#. The next chapter will tackle the details of inheritance and polymorphism.

C# Access Modifiers

When working with encapsulation, you must always take into account which aspects of a type are

visible to various parts of your application. Specifically, types (classes, interfaces, structures, enu-

merations, delegates) and their members (properties, methods, constructors, fields, and so forth)

are always defined using a specific keyword to control how “visible” the item is to other parts of

your application. Although C# defines numerous keywords to control access, they differ on where

they can be successfully applied (type or member). Table 5-1 documents the role of each access

modifier and where it may be applied.
