Hi,
Lets say I have the following classes::
public abstract class Animal
public abstract class MeatEater : Animal
public abstract class PlantEater : Animal

public class Dog : MeatEater

Lets say I create an instance of Dog. I now want to determine if Dog is a meateater or Planteater, how would this be done?

Thank you.

Hi o3h;

By using the "is" operator, see code snippet.

Fernando
Dog dog = new Dog();
 
if (dog is MeatEater)
{
    Console.WriteLine("Dog is a MeatEater");
}
else
{
    Console.WriteLine("Dog is NOT a MeatEater");
}
 
 
if (dog is PlantEater)
{
    Console.WriteLine("Dog is a PlantEater");
}
else
{
    Console.WriteLine("Dog is NOT a PlantEater");
}
