コード
using System; namespace sample14_1 { abstract class Animal { private int weight; private string name; public Animal(int weight, string name) { this.weight = weight; this.name = name; } abstract public void Speak(); abstract public void Move(); public override string ToString() { return String.Format("Name: {0}, Weight: {1}", name, weight); } } class Cat: Animal { public Cat(int weight, string name) : base(weight, name) {} public override void Speak() { Console.WriteLine("にゃーにゃー"); } public override void Move() { Console.WriteLine("スルスル"); } public override string ToString() { return string.Format("[Cat] {0}", base.ToString()); } } class Dog: Animal { public Dog(int weight, string name) : base(weight, name) { } public override void Speak() { Console.WriteLine("わんわん"); } public override void Move() { Console.WriteLine("テクテク"); } public override string ToString() { return string.Format("[Dog] {0}", base.ToString()); } } class Program { static void Main(string[] args) { Cat cat = new Cat(10, "cat1"); Dog dog = new Dog(20, "dog1"); Animal[] animals = { cat, dog }; foreach (var item in animals) { Console.WriteLine(item); } } } }
