Note

As shown in Chapter 13, C# 2008 provides a new object initialization syntax, which allows you to set the

values of public fields and invoke public properties at the time of construction.

The Role of the Default Constructor

Every C# class is provided with a freebee default constructor that you may redefine if need be. By

definition, a default constructor never takes arguments. Beyond allocating the new object into

memory, the default constructor ensures that all field data is set to an appropriate default value

(see Chapter 3 for information regarding the default values of C# data types).

If you are not satisfied with these default assignments, you may redefine the default construc-

tor to suit your needs. To illustrate, update your C# Car class as follows:

class Car

{

// The 'state' of the Car.

public string petName;

public int currSpeed;
