测试远程代理是否有效？

我在客户端和服务器之间使用远程处理，虽然它有效，但我看到了一些我不理解的行为。

我的服务器设置如下：

        BinaryServerFormatterSinkProvider serverProv = new BinaryServerFormatterSinkProvider();
        serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;            
        BinaryClientFormatterSinkProvider clientProv = new BinaryClientFormatterSinkProvider();

        IDictionary props = new Hashtable();
        props["name"] = "MarsLogServer.rem";
        props["port"] = Properties.Settings.Default.ListeningPort;
        props["useIpAddress"] = false;

        server = new LogServer();

        chan = new TcpChannel(props, clientProv, serverProv);
        ChannelServices.RegisterChannel(chan, true);            
        RemotingConfiguration.RegisterWellKnownServiceType(typeof(LogServer), "MarsLogServer.rem", WellKnownObjectMode.Singleton);

我的客户端连接如下：

this.logServer = (ILogServer)Activator.GetObject(typeof(ILogServer), connectForm.Url);
this.logServer.AttachClient(this, connectForm.SessionKey)

发生的情况是我什至没有运行服务器，但我对客户端收到的代理上的 AttachClient() 调用成功。我不明白为什么，没有进程在提供的 URL 上运行托管对象（除非有人对我玩卑鄙的把戏），那么为什么它不抛出异常呢？

理想情况下，我希望调用失败，或者我想要某种方法来测试我的代理是否有效，然后再允许我的客户端继续。现在无法知道连接是否成功。

I'm using remoting between a client and server, and while it works, I'm seeing some behavior I don't understand.

I'm setting up my server as follows:

        BinaryServerFormatterSinkProvider serverProv = new BinaryServerFormatterSinkProvider();
        serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;            
        BinaryClientFormatterSinkProvider clientProv = new BinaryClientFormatterSinkProvider();

        IDictionary props = new Hashtable();
        props["name"] = "MarsLogServer.rem";
        props["port"] = Properties.Settings.Default.ListeningPort;
        props["useIpAddress"] = false;

        server = new LogServer();

        chan = new TcpChannel(props, clientProv, serverProv);
        ChannelServices.RegisterChannel(chan, true);            
        RemotingConfiguration.RegisterWellKnownServiceType(typeof(LogServer), "MarsLogServer.rem", WellKnownObjectMode.Singleton);

And my client is connecting as follows:

this.logServer = (ILogServer)Activator.GetObject(typeof(ILogServer), connectForm.Url);
this.logServer.AttachClient(this, connectForm.SessionKey)

What's happening is I don't even have the server running, but my call to AttachClient() on the proxy my client receives succeeds. I don't understand why that is, there's no process running hosting an object on the provided URL (unless someone is playing a mean trick on me) so why doesn't it throw an exception?

Ideally I'd like the call to fail, or I'd like some way to test that my proxy is valid before allowing my client to proceed. As it is now there's no way of knowing if the connection was successful or not.
