结合项目实例 回顾传统设计模式（十一）代理模式

所谓的代理，就是代表某个真实的对象。在这个设计模式中，代理可以假装自己是远程对象，但其实只是一个中间角色。客户对象所作的就像是在做远程方法调用，但其实只是调用本地资源中得“代理”对象上得方法，再由代理处理所有网络通信的底层细节。

其实其实项目实例神马的 根本就没必要了 看一下Web Service的调用方式大家也许就明白了，它会在客户端生成一个代理类 - - 已经很完美的诠释了代理模式这个概念

虫子放下水 直接拿以前监控项目中客户端采集的代理方法了 --_____--

服务器端

        [WebMethod]
        public void Mem_handleforM(string value,int monitorid)
        {
            try
            {
                string IpInfo = WebUtils.GetClientIP();

                View_Mem vm = new View_Mem();
                vm.Ip = IpInfo;
                vm.MonitorTime = DateTime.Now;
                vm.Value = value;
                vm.monitorid = monitorid;
                //ViewService vs = new ViewService();

                ViewService.Instance.AddMemValue(vm);
            }
            catch (Exception ex)
            {
                ExceptionHandler.Instance.HandleException(ex);
            }


        }

代理

        {
            return base.Channel.Mem_handleforM(request);
        }

        public void Mem_handleforM(string value, int monitorid)
        {
            ProxyService.ReceiveVService.Mem_handleforMRequest inValue = new ProxyService.ReceiveVService.Mem_handleforMRequest();
            inValue.Body = new ProxyService.ReceiveVService.Mem_handleforMRequestBody();
            inValue.Body.value = value;
            inValue.Body.monitorid = monitorid;
            ProxyService.ReceiveVService.Mem_handleforMResponse retVal = ((ProxyService.ReceiveVService.ReceiveVSoap)(this)).Mem_handleforM(inValue);
        }
    }

客户端

  ProxyService.ReceiveVService.ReceiveVSoapClient rv = new ReceiveVSoapClient();
                    rv.Mem_handleforM(value, mc.MemoryConfig_MID);

总结：代理模式为另一个对象提供代表，以便控制客户对对象的访问，管理访问的方式有很多种。远程代理管理客户和远程对象之间的交互。
