Remoting访问的问题,请高手不吝赐教

如何在服务器端获取客户端访问的端口(服务器端开启了多个端口供客户端访问)

[wzkqqq]

我的意思是说:不需要客户端发送类似的信息,直接通过服务器自行检测得到访问的哪个端口

[wzkqqq]

我想 在客户端向服务器发送的远程对象里面应该包含类似的如IP,端口,对象类型等信息吧
应该有方法可以把这个信息取出来,只是我没有找到

[withcsharp]

// Summary:
// Defines how well-known objects are activated.
[Serializable]
[ComVisible(true)]
public enum WellKnownObjectMode
{
// Summary:
// Every incoming message is serviced by the same object instance.
Singleton = 1,
//
// Summary:
// Every incoming message is serviced by a new object instance.
SingleCall = 2,
}

你用的 SingleCall？
要区分吗

[wzkqqq]

我是因为别的原因要区分,总之是想要区分,想要获取对象是通过多个端口中的哪一个传入的

[withcsharp]

IAuthorizeRemotingConnection 可以吗？

[wzkqqq]

withcsharp()
能说的具体点吗

[withcsharp]

IAuthorizeRemotingConnection 接口提供了一些方法，可根据客户端的网络地址和用户标识来指示客户端是否被授权连接至当前信道。


public TcpServerChannel (
IDictionary properties,
IServerChannelSinkProvider sinkProvider,
IAuthorizeRemotingConnection authorizeCallback
)

我怎么获得呢 愿闻其详

[huangyj]

用不同的端口方法不好，这样如果用户多岂不是要开N个端口？

[wzkqqq]

这已经定下来了 我只能做了
我也认为不好,不过没事 我们这是内部使用的 用户不会很多

我想应该可以实现的,大家帮忙顶啊 谢了

[wzkqqq]

有很多信息是根据端口设置的
我想肯定是有办法获得的,有没有人知道啊,
问题还没有解决,大家多帮忙顶下,

[lcg200x]

把用户id传过来

[wzkqqq]

我不想用传值的方法,从服务端直接获得的更好些吧

[wzkqqq]

顶,大家帮帮忙,一定有人知道的

[haiwangstar]

用不同的端口來區分不同用戶這不是一個好辦法。

[wzkqqq]

谢谢 withcsharp()
我正在看...

[wzkqqq]

还是先结了吧,
很感谢,withcsharp()
最后的结果 我做好后再贴出来给大家.
