接口就是对接口内方法实现一种公开调用的形式,可以迅速有效的调用方法而不用每次都去声明实例化:

使用接口时先定义一个接口(接口为黄色),接口内有一个方法,

interface Interface1
    {
        float GetTemperature();
    }

class Thermomrterm
    {
        public void ShowTemperature(Interface1 it)
        {
            Console.WriteLine("温度是:{0}",it.GetTemperature());
        }
    }

class Snake : Interface1
    {
        private float temperature;
        public Snake(float temperature)
        {
            this.Temperature = temperature;
        }

        public float Temperature
        {
            get
            {
                return temperature;
            }

            set
            {
                temperature = value;
            }
        }

        public float GetTemperature()
        {
            return temperature;
        }
    }

class Person:Interface1
    {
        private float temperature;

        public Person(float temperature)
        {
            this.Temperature = temperature;
        }

        public float Temperature
        {
            get
            {
                return temperature;
            }

            set
            {
                temperature = value;
            }
        }

        public float GetTemperature()
        {
            return Temperature;
        }
    }

public static void Tesk01()
        {
            Interface1[] its = new Interface1[2];
            its[0] = new Snake(123.4f);
            its[1] = new Person(36.9f);
            Thermomrterm th = new Thermomrterm();
            for (int i = 0; i < its.Length; i++)
            {
                th.ShowTemperature(its[i]);
            }
        }

static void Main(string[] args)
        {
            Tesk01();
        }
