CHAPTER 2 BUILDING C# APPLICATIONS
By way of example, drag a new Class from the Class Designer Toolbox onto your Class Designer.
Name this class Car in the resulting dialog box. Now, using the Class Details window, add a public string
field named petName (see Figure 2-20).
Figure 2-20. Adding a field with the Class Details window
If you now look at the C# definition of the Car class, you will see it has been updated accordingly
(minus the additional code comments seen below).
public class Car
{
// Public data is typically a bad idea; however,
// it keeps this example simple.
public string petName;
}
Now, activate the designer file once again and drag another new Class onto the designer and name
it SportsCar. Now, select the Inheritance icon from the Class Designer Toolbox and click the top of the
SportsCar icon. Next, click the mouse on top of the Car class icon. If you performed these steps correctly,
you have just derived the SportsCar class from Car (see Figure 2-21).
