Исключение при общении с удаленным сервером?

Question

я установил связь с удаленным server..The удаленный сервер выставил event.When я пытаюсь подписаться на событие я получаю исключение с последующим трассировки стека

    = {"Exception has been thrown by the target of an invocation."}

Мой код блока выглядит следующим образом: конфигурация для удаленного взаимодействия сервера приведена ниже // код

TurnOffRemotingExceptionFiltering(); 

BinaryClientFormatterSinkProvider^ clientProvider = nullptr; 
BinaryServerFormatterSinkProvider^ serverProvider = gcnew aryServerFormatterSinkProvider(); 
serverProvider->TypeFilterLevel = TypeFilterLevel::Full; 
System::Collections::IDictionary^ props = gcnew Hashtable(); 
props["port"] = port; 
String^ guid = System::Guid::NewGuid().ToString(); 
props["typeFilterLevel"] = TypeFilterLevel::Full; 

//TcpChannel 
channel = gcnew TcpChannel(props, clientProvider, serverProvider); 
ChannelServices::RegisterChannel(channel, false); 
props["name"] = guid; 

void RemoteConnectionManager::TurnOffRemotingExceptionFiltering() 
{ 
       // Gets the assembly in which the 'System.Runtime.Remoting.RemotingConfiguration' is defined. 
       Assembly^ remoting = Assembly::GetAssembly(RemotingConfiguration::typeid); 

       // Gets the Type object of 'System.Runtime.Remoting.CustomErrorsModes' from assembly instance. 
       Type^ customErrorsModes = remoting->GetType("System.Runtime.Remoting.CustomErrorsModes"); 

       // Gets the Type object of 'System.Runtime.Remoting.RemotingConfigHandler' from assembly instance. 
       Type^ remotingConfigHandler = remoting->GetType("System.Runtime.Remoting.RemotingConfigHandler"); 

       // Gets details of '_errorMode' field.'_errorMode' indicates whether the server channels in 
       // this application domain return filtered or complete exception information to local or remote callers. 
       FieldInfo^ errorMode = remotingConfigHandler->GetField("_errorMode", 
             BindingFlags::Static | BindingFlags::NonPublic); 

       // Gets details of 'Off' field.'System.Runtime.Remoting.CustomErrorsModes' is an Enumeration 
       FieldInfo^ mode = customErrorsModes->GetField("Off"); 

       // Sets "Off" to get to get complete exception information 
       // from server channels to to local or remote callers. 
       errorMode->SetValue(nullptr, mode->GetValue(nullptr)); 
      }

в случае распределенных систем нам нужно класс-оболочку для обмена данными с сервером и client..We не может подписаться непосредственно на событие без обертки class..Эта оболочка cl задница выступает в качестве среды для связи с клиентом и сервером.
