Microsoft® Visual C#® 2005 Step by Step

Chapter 9. Creating Value Types with Enumerations and Structs

After completing this chapter, you will be able to:

• Declare an enumeration type.

• Create and use an enumeration type.

• Declare a structure type.

• Create and use a structure type.

In Chapter 8, you learned about the two fundamental kinds of types that exist in Microsoft Visual C#: value types and reference types. A value type variable holds its value directly on the stack, whereas a reference type variable holds a reference to an object on the heap. In Chapter 7, you learned how to write your own classes, thus creating your own reference types. In this chapter, you’ll learn how to write your own value types.

C# supports two kinds of value types: enumerations and structures.
