Question

I have an Array of AutoMobiles
This array may contain SubClass Objects Truck or Car.

How do I test a Position in the Array for the type of Object?
eg:

if(AutoMobileArray[1].IsObject(Car)){}

The Car Class has a unique Accessor

public String BootSpace()

How can I use the SubClass Objects Accessors?
eg:

if(AutoMobileArray[1].IsObject(Car))
{
    BootSpaceLabel.Text = AutoMobileArray[1].BootSpace();
}

Well, If I understand you correctly, there’s the is operator:

if(AutoMobileArray[1] is Car)
{
  //Do stuff here
}

To do stuff with the subclass (access methods defined in the subclass etc.) you need to cast:

if(AutoMobileArray[1] is Car)
{
  Car c = (Car)AutoMobileArray[1];
}
