////先定义接口

using System;using System.Text;namespace IComm{    /// <summary>    /// send messages delegate    /// </summary>    /// <param name="Ms"></param>    public delegate void SendEventHandler(string Ms);    public interface ICom    {        /// <summary>        /// send function        /// </summary>        /// <param name="Ms"></param>        /// <returns></returns>        void SendMs(string Ms);    }}

////obj类
