[游戏开发]【C#】【OOP】隐藏和重写

隐藏 ， 声明的类型会影响调用的方法是父类还是子类

using System;


namespace HelloOOP
{
    class Program
    {
        static void Main(string[] args)
        {
            Vehicle car = new Car();
            car.Run();  //Vehicle run

            Car car2 = new Car();
            car2.Run();  //Car run

			new Car().Run(); //Car run
        }
    }


    class Vehicle
    {
        public void Run()
        {
            Console.WriteLine("Vehicle run");
        }
    }

    class Car : Vehicle
    {
        public void Run()
        {
            Console.WriteLine("Car run");
        }
    }
}

重写 ， 不受声明类型的影响 ，根据实例的类型调用方法

using System;


namespace HelloOOP
{
    class Program
    {
        static void Main(string[] args)
        {
            Vehicle car = new Car();
            car.Run();  //Car run

            Car car2 = new Car();
            car2.Run();  //Car run
        }
    }


    class Vehicle
    {
        public virtual void Run()
        {
            Console.WriteLine("Vehicle run");
        }
    }

    class Car : Vehicle
    {
        public override void Run()
        {
            Console.WriteLine("Car run");
        }
    }
}
