NET Framework doesn??™t already know about.
Chapter 10, ???Arrays and Collections,??? covers the various array and collection types available
in VB 2008. You can create two types of multidimensional arrays, as well as your own
collection types, while utilizing collection-utility classes. You??™ll also learn how to implement
IEnumerable so that your collection types will work well with For . . . Each statements.
Chapter 11, ???Delegates and Events,??? shows you the mechanisms used within VB 2008 to
provide callbacks. Historically, all viable frameworks have always provided a mechanism to
implement callbacks. VB 2008 goes one step further and encapsulates callbacks into callable
objects called delegates. Also, you??™ll see how the .NET Framework builds upon delegates to
provide a publish-subscribe event-notification mechanism, allowing your design to decouple
the source of the event from the consumer of the event.
Chapter 12, ???Generics,??? introduces you to probably the most exciting feature added to
VB 2008 and the CLR. Using generics, you can provide a shell of functionality within which to
define more specific types at run time. Generics are most useful with collection types and
provide great efficiency compared to the collections of previous .
