//为消息类型声明对应的处理器  
NetworkComms.AppendGlobalIncomingPacketHandler<UserInfo>("UserLogin", IncomingLoginHandler);

 //第三个参数为客户端发来的实际契约类类型，networkcomms通信框架自动把二进制数据解析为此类型数据
 private void IncomingLoginHandler(PacketHeader header, Connection connection, UserInfo userInfo)

                string userID = userInfo.UserID;
                string passWord = userInfo.Password;

                //从数据库中验证用户名和密码
               if (验证成功)
                    //给契约类实例赋值
                    resMessage.Message = "登录成功";
