C #-----Polymorphism

The concept of polymorphism: The same method is called by different objects implemented by inheritance, which shows different behaviors, called polymorphic

Override Implementing Polymorphic

 Public classAnimal { Public Virtual voidEat () {Console.WriteLine ("Animal Eat"); }    }     Public classDog:animal { Public Override voidEat () {Console.WriteLine ("Dog Eat"); }    }     Public classWolfdog:dog { Public Override voidEat () {Console.WriteLine ("Wolfdog Eat"); }    }    classTester {Static voidMain (string[] args) {animal[] Animals=Newanimal[3]; animals[0] =NewAnimal (); animals[1] =NewDog (); animals[2] =NewWolfdog ();  for(inti =0; I <3; i++) {Animals[i].            Eat (); }        }}

Abstract-override Implementing Polymorphic

 Public Abstract classAnimal { Public Abstract voidEat (); }     Public classCat:animal { Public Override voidEat () {Console.WriteLine ("Cat Eat"); }    }     Public classDog:animal { Public Override voidEat () {Console.WriteLine ("Dog Eat"); }    }     Public classWolfdog:dog { Public Override voidEat () {Console.WriteLine ("Wolfdog Eat"); }    }    classTester {Static voidMain (string[] args) {animal[] Animals=Newanimal[3]; animals[0] =NewCat (); animals[1] =NewDog (); animals[2] =NewWolfdog ();  for(inti =0; I < animals. Length; i++) {Animals[i].            Eat (); }        }    }
