Recall: Conversions Among Related Class Types

As shown in Chapter 6, class types may be related by classical inheritance (the “is-a” relationship).

In this case, the C# conversion process allows you to cast up and down the class hierarchy. For

example, a derived class can always be implicitly cast to a base type. However, if you wish to store

a base class type in a derived variable, you must perform an explicit cast:

C H A P T E R   1 2  

■

I N D E X E R S, O P E R ATO R S, A N D   P O I N T E R S
