那位高手给一个Remoting的例子看看！小弟没装MSDN！(在线等待！急急急！！)

[apollonew]

Server.cs （服务器）
Client.cs （客户端）
RemoteObj.cs （远程对象）
IRemote.cs （远程对象接口）

采用 Client 调用 IRemote 来使用 Server 的 RemoteObj ！
我想在 Server 里实现 访问 数据库！返回一个 DataView
所有的数据访问方法都不要在 RemoteObj 里实现！
RemoteObj 只是把访问的结果 DataView 返回给 Client 就行了！
请高手高手高高手指点一二！

分不够再加！！：）

如果要保证安全的话，应把服务器端与接口分开，客户端用接口时使用Activator.GetObject取到Remoting对象，再使用对象中的方法。

[apollonew]

~上面的例子太复杂了~能不能搞个简单的！
只是能说明一下我要的那个例子就行了！

[apollonew]

有没有高手指点一下啊！
我主要是想知道怎么在 Client 使用接口的方法啊！

还有就是 DataView 怎么返回给 Client！ 当然前提条件是 SqlConnection 不要做在
RemoteObj 里面！

拜托啦！！！搞定后当场结算~~
不够再开新贴给分

[apollonew]

up

[apollonew]

理论我知道啊！但用代码怎么做呢？！？？！
有没有人给个例子我看看啊！！谢谢啦！很急的啊

[apollonew]

up 一下啊！！救我啊
