【C#】【设计模式六大原则】接口隔离原则

接口隔离原则

客户端不应该依赖它不需要的接口；一个类对另一个类的依赖应该建立在最小的接口上。

using System;

namespace LspExample
{
    class Program
    {
        static void Main(string[] args)
        {
            var driver = new Driver(new LightTank());
            //var driver = new Driver(new Car());
            driver.Drive();
        } 
    }

    class Driver
    {
        private IVehicle _vehicle; //最小依赖
        public Driver(IVehicle vehicle)
        {
            _vehicle = vehicle;
        }
        public void Drive()
        {
            _vehicle.Run();
        }
    }

    interface IWeapon
    {
        void Fire();
    }

    interface IVehicle
    {
        void Run();
    }

    //interface ITank
    //{
    //    void Fire();
    //    void Run();
    //}
    interface ITank : IVehicle, IWeapon
    {

    }

    class Car : IVehicle
    {
        public void Run()
        {
            Console.WriteLine("Car is running...");
        }
    }
    class Truck : IVehicle
    {
        public void Run()
        {
            Console.WriteLine("Truck is running...");
        }
    }

    class LightTank : ITank
    {
        public void Fire()
        {
            Console.WriteLine("Boom!");
        }

        public void Run()
        {
            Console.WriteLine("ka ka ka...");
        }
    }

    class MediumTank : ITank
    {
        public void Fire()
        {
            Console.WriteLine("Boom!!");
        }

        public void Run()
        {
            Console.WriteLine("ka ka ka......");
        }
    }
}
