Chapter 8. Understanding Values and References

After completing this chapter, you will be able to:

  • Explain the differences between a value type and a reference type.

  • Modify the way in which arguments are passed as method parameters by using the ref and out keywords.

  • Box a value by initializing or assigning a variable of type object.

  • Unbox a value by casting the object reference that refers to the boxed value.

In Chapter 7 you learned how to declare your own classes and how to create objects by using the new keyword. You also saw how to initialize an object by using a constructor. In this chapter, you will learn about how the characteristics of the primitive types—such as int, double, and char—differ from the characteristics of class types.
