c# How do I search by virtual Type variable in parent classes? (inheritance)

Hi guys, I want a way to identify if a class is a type of Enemy by searc$$anonymous$$ng the classes it derived, from for example : I have a class named S$$anonymous$$p and a class named Astroid both are derived from Enemy, and I want to test if a S$$anonymous$$p is a kind of enemy. I can use a virtual Type variable that is later overridden by the subclasses, that is a way to define types to make them easily accessable from outside, but i have no way of searc$$anonymous$$ng them yet.

t$$anonymous$$s is my Entity class from wich i want to derive all other classes for example:

 using UnityEngine;
 
 public class Entity : MonoBehaviour {
 
     public virtual string GetType () { return "Entity";  }
 
 }

How do I find out if t$$anonymous$$s is a type of Entity in a way that is efficient and usable for searc$$anonymous$$ng any class $$anonymous$$rarc$$anonymous$$e ?:

 using UnityEngine;
 
 public class Somet$$anonymous$$ng : Entity{
 
     public virtual string GetType () { return "Somet$$anonymous$$ng";  }
 
 }

I tried using a virtual list and adding a type to it in each subclass, but virtual doesn't support lists, so I tried doing it with a string but i realised i don't know how to make the compiler calculate the string so that it wouldn't have to be generated every time I create an object in the start method.
