In my understanding, different objects implemented by inheritance call the same method and show different behaviors, called polymorphism.1: override achieves Polymorphism 1 public class Animal 2 { 3 public virtual void Eat() 4 {

Overload: in the same class, the method name is the same, and the parameter list is different. Different parameter lists include: the number of parameters is different, and the parameter type is different. 1 using system; 2 using system. collections.

1. Before learning enumeration, first listen to the advantages of enumeration. 1. Enumeration makes the code clearer. It allows descriptive names to represent integer values. 2. Enumeration makes the code easier to maintain and helps to specify
