Classes are very useful for building hierarchies of objects. For example, you could create a class called VEHICLE. You could then create two classes CAR and MOTORCYCLE which both inherited from the VEHICLE class. Although the two classes are very different, they have alot of the same base data (let’s say EngineSpeed, GearRatio).
If you wanted to find out how fast a vehicle was going, you could call:
public void GetSpeed(Vehicle vehicle)
{
return (vehicle.EngineSpeed * vehicle.GearRatio);
}
You could call this function with a class of either CAR or MOTORCYCLE as they both come from the VEHICLE base class. If you weren’t using classes, you would need to write a seperate function for each of these. Obviously this function is pretty lame, but hopefully it gives you an idea for one of the important uses of classes.
If you need any help with C#, I’m more than happy to give a hand, although you probably realize more than most how important searching and learning on your own is.
