Question

我一直在尝试在我的组件之间进行远程通信（两者都在同一台PC上）并且我得到了许多不同的例外，我真的不知道发生了什么，因为我没有在龙中使用远程处理时间，也许你可以帮我一把。

这是异常的堆栈跟踪：

这是我用于远程服务器的代码：

BinaryServerFormatterSinkProvider formatServ = new BinaryServerFormatterSinkProvider();

//propiedades nombre y puerto del servidor
IDictionary props = new Hashtable();
props["name"] = "Canal";
props["port"] = 8989;
try
{
    TcpChannel channel = new TcpChannel(props, null, formatServ);
    ChannelServices.RegisterChannel(channel, false);
    RemotingConfiguration.RegisterWellKnownServiceType(
        typeof(FactoryPersistencia),
        "FabricaPersistencia",
        WellKnownObjectMode.Singleton
        );
    Console.WriteLine("Servidor de Remoting Levantado...");
    Console.WriteLine("Presione una tecla para terminar.");
    Console.ReadLine();
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
    Console.ReadKey();
}

以下是我用于客户的代码：

TcpChannel chan = new TcpChannel();
ChannelServices.RegisterChannel(chan, true);
RemotingConfiguration.RegisterWellKnownClientType(typeof(FactoryPersistencia), "tcp://localhost:8989/FabricaPersistencia");

FactoryPersistencia fabricaPers = FactoryPersistencia.getInstance();


IPUsuario ipus = fabricaPers.GetFachadaUsuario();

以下是正在调用的工厂代码：

public class FactoryPersistencia : MarshalByRefObject
{
    //Singleton
    private static FactoryPersistencia instancia = null;

    public static FactoryPersistencia getInstance(){

        if (instancia == null)
            instancia = (FactoryPersistencia)Activator.GetObject(typeof(FactoryPersistencia), "tcp://localhost:8989/FabricaPersistencia");

        return instancia;
    }

    public IPUsuario GetFachadaUsuario()
    {
        return new PersistenciaUsuario();
    }
    public IPEvento GetFachadaEvento() { 
        return new PersistenciaEvento();
    }
    public IPAmistad GetFachadaAmistad()
    {
        return new PersistenciaAmistad();
    }
}

谢谢大家，我很抱歉我无法上色，这实际上是我的第一个问题。

将远程服务器中的ChannelServices.RegisterChannel(channel, false);更改为ChannelServices.RegisterChannel(channel, true);。您的客户端要求提供安全通道，但服务器未提供安全通道。

您也可以从客户端删除RemotingConfiguration.RegisterWellKnownClientType(typeof(FactoryPersistencia), "tcp://localhost:8989/FabricaPersistencia");。
