C# - 在类中使用多态,我没写

using System;

public class Animal
{
    public virtual void MakeSound()
    {
        Console.WriteLine("The animal makes a sound");
    }
}

public class Dog : Animal
{
    public override void MakeSound()
    {
        Console.WriteLine("The dog barks");
    }
}

public class Cat : Animal
{
    public override void MakeSound()
    {
        Console.WriteLine("The cat meows");
    }
}

public class Program
{
    public static void Main()
    {
        Animal[] animals = new Animal[] { new Dog(), new Cat() };

        foreach (Animal animal in animals)
        {
            animal.MakeSound();
        }
    }
}
