Remote建立分析
Remote作为一个远程调用对象技术,它有着.WebService没有的优势,首先它在一个企业内部系统使用的话,TCP通常就更好地发挥它的作用,当然它不跨平台这是一个不少的遗憾,下面是我对Remote的一点了解,有错误的地方大家指出来..
Remote通常分三步建立
1: RemoteObject(通常是类库文件)
2: RemoteServer(真正开发项目的时间建议用WINDOWS服务,调试的时候可以用控制台程序)
3: RemoteClient(也就是实现RemoteObject所定义的方法)
RemoteObject
(一):定義對象接口(如: interface ISenLin)
1:定義屬性
2:定義方法
3:其他
如:
(二):定義工廠接口(interface IMyFactory)作用:創建對象接口實例
1:定義返回接口實例的方法
2:其他
RemoteServer
(一):定義對象類並繼承MarshalByRefObject類和實現對象接口
如: public class SenLin:MarshalByRefObject,ISenLin
(二):定義工廠類並繼承MarshalByRefObject類和實現工廠接口
(注:通常上面两个是在RemoteObject中实现,只是当初为了表示更好的理解而在这里实现
)
如: public class ServerFactory:MarshalByRefObject,IMyFactory
(三):注冊通道
如: TcpChannel chan = new
TcpChannel(7777);
HttpChannel chan2 = new HttpChannel(8888);
(四):注冊對象(即工廠類ServerFactory)
如: RemotingConfiguration.RegisterWellKnownServiceType(typeof(ServerFactory),
"senlin", WellKnownObjectMode.SingleCall);
RemoteClient
(一):注冊通道
如: TcpChannel chan = new
TcpChannel();
HttpChannel
chan2 = new HttpChannel();
(二): 客戶端激活
1: 激活創建工廠接口對象
2: 通過工廠對象接口的實例方法返回對象接口實例
如:IMyFactory imyf = (IMyFactory)Activator.GetObject(typeof(IMyFactory), "tcp://localhost:7777/longkc");
ISenLin isen =
imyf.GetSenLin();
(三): 通過對象接口的實例可以實現對象接口所定義的方法和屬性等
總結:
1在OBJECT中定義工廠接口和對象接口
2:在SERVER中定義工廠類實現工廠接口,定義對象類實理對象接口, 注冊對象(即工廠類)
3:在CLIENT 中激活工廠接口,創建對象接口, 用對象接口實現定義的屬性和方法
