C# 程序设计，设计抽象类Animal，具有类别、速度等属性，具有吃、叫、喜好等抽象方法；设计派生类Dog 、Cat实现抽象方法...比较对象的速度，并给出结果

/// 

/// 抽象类：动物
/// 
public abstract class Animal {
    protected string type;
    protected int speed;

    public string Type => type;
    public int Speed => speed;

    public abstract void Talk();
    public abstract void Eat();
    public abstract void Love();

    public override string ToString() {
        return type;
    }
}

/// 

/// 实现类：猫
/// 
public class Cat:Animal {
    public Cat(string type,int speed) {
        this.type = type;
        this.speed = speed;
    }

    public override void Talk() {
        System.Console.WriteLine("喵喵");
    }

    public override void Eat() {
        System.Console.WriteLine("吃鱼");
    }

    public override void Love() {
        System.Console.WriteLine("捉老鼠");
    }
}

/// 

/// 实现类：狗
/// 
public class Dog:Animal {

    public Dog(string type, int speed) {
        this.type = type;
        this.speed = speed;
    }

    public override void Talk() {
        System.Console.WriteLine("汪汪");
    }

    public override void Eat() {
        System.Console.WriteLine("吃肉");
    }

    public override void Love() {
        System.Console.WriteLine("狩猎");
    }
}

using System;

namespace _3_1 {
    class Program {
        static void Main(string[] args) {

            Animal cat = new Cat("波斯猫", 30);
            Animal dog = new Dog("猎犬", 60);
            //调用行为
            cat.Talk();
            cat.Eat();
            cat.Love();
            //调用行为
            dog.Talk();
            dog.Eat();
            //dog.Love();

            输出属性，重载ToString
            PrintPropertys(cat);
            PrintPropertys(dog);
            比较
            Console.WriteLine($"速度更快的是：{(cat.Speed > dog.Speed ? cat.Type : dog.Type)}");
            Console.ReadLine();

        }

        static void PrintPropertys(Animal animal) {
            Console.WriteLine($"类型：{animal.Type}， 速度：{animal.Speed}");
        }
    }
}

运行结果：
