Properties

As we’ve seen, properties are characteristics shared by all objects of a particular

class. In the case of our example, the following properties might be used to describe

any given dog:

❑

color

❑

height

❑

length

In the same way, the more useful ASP.NET Button class exposes properties in-

cluding:

❑

Width

❑

Height

❑

ID

❑

Text

❑

ForeColor

❑

BackColor

Unfortunately for me, if I get sick of Rayne’s color, I can’t change it in real life.

However, if Rayne was a .NET object, we could change any of his properties in

the same way that we set variables (although a property can be read-only or write-

only). For instance, we could make him brown very easily:

Visual Basic

rayne.Color = "Brown"

C#

rayne.Color = "Brown";

In this example, we’re using an instance of our Dog class called rayne. We use

the dot operator (.) to access the property Color that the object exposes and set

it to the string "Brown."
