c# - How to access a value attached to a derived class? -

i have class called animal. given animal a, a.number_of_legs should 4.

i have class called human inherits animal. given human h, h.number_of_legs should 2.

how set number_of_legs property?

---

here's have far:

 class animal {       int number_of_legs = 4;  }   class human : animal {       int number_of_legs = 2;  } 

but if take arbitrary animal , ask how many legs has, answer 2:

 animal x = new animal();  animal y = new human();  x.number_of_legs // --> 4  y.number_of_legs // --> 4 

i understand new human being treated animal because variable y stores animal.

how set number_of_legs property x.number_of_legs 4 , y.number_of_legs 2?

first of all, should using actual c# properties publicly accessible values this, not public fields.

mark property virtual in base class can overridden in derived classes.

public class animal {      // default, animals have 4 legs.     public virtual int numberoflegs { { return 4; } } } 

then override in derived class provide different implementation.

public class human : animal {      // humans have 2 legs.     public override int numberoflegs { { return 2; } } }
