In the previous chapters, you worked with simple data types—namely, Integer and String variables. Although these data types are useful in their own right, more complex programs call for working with data structures—groups of data elements that are organized in a single unit. In this chapter, you learn about the various data structures available in Visual Basic 2015. You also will see some ways in which you can work with complex sets of data. Finally, you learn how you can build powerful collection classes for working with, maintaining, and manipulating lists of complex data.
