自己写的接口

class InterfaceTest1
    {
        static void Main(string[] args)
        {
            Student stu = new Student();
            stu.sum();
            stu.sum1();
            Console.ReadKey();
        }
    }
    //接口1

    interface Ic1
    {
       
        void sum();
       
    }
    //接口2
    interface Ic2
    {
        void sum1();

    }
    class ss
    {

    }
    class Student:ss,Ic1,Ic2
    {
        //接口实现
        public void sum()
        {
            Console.WriteLine("接口1");
        }
        public void sum1()
        {
            Console.WriteLine("接口2");
        }
    }
