同接口的方法不同参数个数处理

    class Program
    {
        public abstract class ParamBase { }

        public  class TCPParam : ParamBase
        {
            public string IP { get; set; }
            public string Port { get; set; }
        }
      public   class SeialPortParam : ParamBase
        {
            public string bote { get; set; }
        }
     
        interface ITX
        {
            void Init(ParamBase param);

        }

        class TCPTX : ITX
        {
            TCPParam _param;


            public void Init(ParamBase param)
            {
                _param = param as TCPParam;
                Console.WriteLine(_param.IP);
                Console.WriteLine(_param.Port);
            }
        }

        class SerilPort : ITX
        {
            SeialPortParam _param;


            public void Init(ParamBase param)
            {
                _param = param as SeialPortParam;
                Console.WriteLine(_param.bote);
                Console.ReadKey();
            }
        }

        static void Main(string[] args)
        {
            ITX tx = new TCPTX();
            TCPParam tCPParam = new TCPParam() { IP = "11", Port = "111" };
            tx.Init(tCPParam);
            tx = new SerilPort();
            SeialPortParam SerilPortParam = new SeialPortParam() { bote = "bote" };
            tx.Init(SerilPortParam);
        }
    }

好用点个赞再走呗~
