원격 서버와 통신하는 동안 예외가 발생 했습니까?

Question

내가 원격 서버가 내가 스택 추적을 다음과 같이 예외를 얻을 이벤트를 구독하려고 event.When을 노출 한 원격 server..The와의 통신을 설립

다음과 같이 내 코드 블록은 다음과 같습니다 은 원격 서버의 구성은 아래와 같습니다 // 코드 우리는 서버와 래퍼없이 이벤트를 직접 등록 할 수 client..We와 통신하기 위해 래퍼 클래스를 필요로 분산 시스템의 경우

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)); 
      }

이 래퍼 cl 엉덩이는 클라이언트와 서버와 통신하는 매체 역할을합니다.
