Changing the Characteristics of Objects
Almost everything you work with in C# is an object. Forms, for instance, are objects, as are all the items you can put on a form to build an interface, such as list boxes and buttons. There are many types of objects (Hour 3, "Understanding Objects and Collections," discusses objects in detail). Objects, in turn, are classified by type. For instance, a form is a Form object, whereas items you can place on a form are called Control objects, or controls. Some objects don't have a physical appearance, but exist only in code. You'll learn about these kinds of objects in later hours.
Every object, regardless of whether it has a physical appearance, has a distinct set of attributes known as properties. You have certain properties about you, such as your height and hair color, and C# objects have properties as well, such as Height and BackColor. Properties define the characteristics of an object. When you create a new object, the first thing you need to do is set its properties so that the object appears and behaves in the way you desire. To display the properties of an object, click the object in its designer. Click the form now to ensure that its properties are displayed in the Properties window.
