Beispiele

Im folgenden Codebeispiel wird gezeigt, wie sie einen IpcChannel verwenden, um einen Remotingserver und dessen Client einzurichten. Das Beispiel enthält drei Teile:

• Ein Server

• Ein Client

• Ein Remoteobjekt, das vom Server und client verwendet wird.

Das folgende Codebeispiel zeigt einen Server.

#using <System.dll>
#using <System.Runtime.Remoting.dll>
#using "common.dll"
using namespace System;
using namespace System::Runtime::Remoting::Channels::Ipc;

void main()
{
   // Create the server channel.
   IpcChannel^ serverChannel = gcnew IpcChannel( L"localhost:9090" );

   // Register the server channel.
   System::Runtime::Remoting::Channels::ChannelServices::RegisterChannel( serverChannel );

   // Show the name of the channel.
   Console::WriteLine( L"The name of the channel is {0}.", serverChannel->ChannelName );

   // Show the priority of the channel.
   Console::WriteLine( L"The priority of the channel is {0}.", serverChannel->ChannelPriority );

   // Show the URIs associated with the channel.
   System::Runtime::Remoting::Channels::ChannelDataStore^ channelData = (System::Runtime::Remoting::Channels::ChannelDataStore^)serverChannel->ChannelData;
   for each (String^ uri in channelData->ChannelUris)
   {
      Console::WriteLine("The channel URI is {0}.", uri);
   }
   
   // Expose an object for remote calls.
   System::Runtime::Remoting::RemotingConfiguration::RegisterWellKnownServiceType(
         RemoteObject::typeid,L"RemoteObject.rem",
         System::Runtime::Remoting::WellKnownObjectMode::Singleton);
   
   // Parse the channel's URI.
   array<String^>^ urls = serverChannel->GetUrlsForUri( L"RemoteObject.rem" );
   if ( urls->Length > 0 )
   {
      String^ objectUrl = urls[ 0 ];
      String^ objectUri;
      String^ channelUri = serverChannel->Parse( objectUrl,  objectUri );
      Console::WriteLine( L"The object URI is {0}.", objectUri );
      Console::WriteLine( L"The channel URI is {0}.", channelUri );
      Console::WriteLine( L"The object URL is {0}.", objectUrl );
   }

   // Wait for the user prompt.
   Console::WriteLine( L"Press ENTER to exit the server." );
   Console::ReadLine();
   Console::WriteLine( L"The server is exiting." );
}

using System;
using System.Runtime.Remoting.Channels.Ipc;

public class Server
{
    public static void Main(string[] args)
    {
        // Create the server channel.
        IpcChannel serverChannel =
            new IpcChannel("localhost:9090");

        // Register the server channel.
        System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(
            serverChannel);

        // Show the name of the channel.
        Console.WriteLine("The name of the channel is {0}.",
            serverChannel.ChannelName);

        // Show the priority of the channel.
        Console.WriteLine("The priority of the channel is {0}.",
            serverChannel.ChannelPriority);

        // Show the URIs associated with the channel.
        System.Runtime.Remoting.Channels.ChannelDataStore channelData =
            (System.Runtime.Remoting.Channels.ChannelDataStore)
            serverChannel.ChannelData;
        foreach (string uri in channelData.ChannelUris)
        {
            Console.WriteLine("The channel URI is {0}.", uri);
        }

        // Expose an object for remote calls.
        System.Runtime.Remoting.RemotingConfiguration.
            RegisterWellKnownServiceType(
                typeof(RemoteObject), "RemoteObject.rem",
                System.Runtime.Remoting.WellKnownObjectMode.Singleton);

        // Parse the channel's URI.
        string[] urls = serverChannel.GetUrlsForUri("RemoteObject.rem");
        if (urls.Length > 0)
        {
            string objectUrl = urls[0];
            string objectUri;
            string channelUri = serverChannel.Parse(objectUrl, out objectUri);
            Console.WriteLine("The object URI is {0}.", objectUri);
            Console.WriteLine("The channel URI is {0}.", channelUri);
            Console.WriteLine("The object URL is {0}.", objectUrl);
        }

        // Wait for the user prompt.
        Console.WriteLine("Press ENTER to exit the server.");
        Console.ReadLine();
        Console.WriteLine("The server is exiting.");
    }
}

Das folgende Codebeispiel zeigt einen Client für diesen Server.

#using <System.dll>
#using <System.Runtime.Remoting.dll>
#using "common.dll"
using namespace System;
using namespace System::Runtime::Remoting::Channels::Ipc;

void main()
{
   
   // Create the channel.
   IpcChannel^ channel = gcnew IpcChannel;
   
   // Register the channel.
   System::Runtime::Remoting::Channels::ChannelServices::RegisterChannel(channel);
   
   // Register as client for remote object.
   System::Runtime::Remoting::WellKnownClientTypeEntry^ remoteType = gcnew
       System::Runtime::Remoting::WellKnownClientTypeEntry( 
         RemoteObject::typeid,L"ipc://localhost:9090/RemoteObject.rem" );
   System::Runtime::Remoting::RemotingConfiguration::RegisterWellKnownClientType(remoteType);
   
   // Create a message sink.
   String^ objectUri;
   System::Runtime::Remoting::Messaging::IMessageSink^ messageSink = channel->CreateMessageSink(
      L"ipc://localhost:9090/RemoteObject.rem", nullptr, objectUri );
   Console::WriteLine( L"The URI of the message sink is {0}.", objectUri );
   if ( messageSink != nullptr )
   {
      Console::WriteLine( L"The type of the message sink is {0}.", messageSink->GetType() );
   }

   
   // Create an instance of the remote object.
   RemoteObject^ service = gcnew RemoteObject;
   
   // Invoke a method on the remote object.
   Console::WriteLine( L"The client is invoking the remote object." );
   Console::WriteLine( L"The remote object has been called {0} times.", service->GetCount() );
}

using System;
using System.Runtime.Remoting.Channels.Ipc;

public class Client
{
    public static void Main(string[] args)
    {
        // Create the channel.
        IpcChannel channel = new IpcChannel();

        // Register the channel.
        System.Runtime.Remoting.Channels.ChannelServices.
            RegisterChannel(channel);

        // Register as client for remote object.
        System.Runtime.Remoting.WellKnownClientTypeEntry remoteType =
            new System.Runtime.Remoting.WellKnownClientTypeEntry(
                typeof(RemoteObject),
                "ipc://localhost:9090/RemoteObject.rem");
        System.Runtime.Remoting.RemotingConfiguration.
            RegisterWellKnownClientType(remoteType);

        // Create a message sink.
        string objectUri;
        System.Runtime.Remoting.Messaging.IMessageSink messageSink =
            channel.CreateMessageSink(
                "ipc://localhost:9090/RemoteObject.rem", null,
                out objectUri);
        Console.WriteLine("The URI of the message sink is {0}.",
            objectUri);
        if (messageSink != null)
        {
            Console.WriteLine("The type of the message sink is {0}.",
                messageSink.GetType().ToString());
        }

        // Create an instance of the remote object.
        RemoteObject service = new RemoteObject();

        // Invoke a method on the remote object.
        Console.WriteLine("The client is invoking the remote object.");
        Console.WriteLine("The remote object has been called {0} times.",
            service.GetCount());
    }
}

Das folgende Codebeispiel zeigt das Remoteobjekt, das vom Server und client verwendet wird.

using namespace System;

// Remote object.
public ref class RemoteObject: public MarshalByRefObject
{
private:
   static int callCount = 0;

public:
   int GetCount()
   {
      Console::WriteLine( L"GetCount has been called." );
      callCount++;
      return (callCount);
   }

};

using System;

// Remote object.
public class RemoteObject : MarshalByRefObject
{
    private int callCount = 0;

    public int GetCount()
    {
        Console.WriteLine("GetCount has been called.");
        callCount++;
        return(callCount);
    }
}

Hinweise

Kanäle werden von the.NET Framework-Remotinginfrastruktur verwendet, um Remoteanrufe zu übertragen. Wenn ein Client ein Remoteobjekt aufruft, wird der Aufruf in eine Nachricht serialisiert, die von einem Clientkanal gesendet und von einem Serverkanal empfangen wird. Nachdem die Nachricht empfangen wurde, wird sie deserialisiert und verarbeitet. Alle zurückgegebenen Werte werden vom Serverkanal übertragen und vom Clientkanal empfangen.

Die IpcChannel -Klasse ist eine Komfortklasse, die die Funktionalität der IpcClientChannel -Klasse und der IpcServerChannel -Klasse kombiniert.
