Beispiele

Im folgenden Codebeispiel wird gezeigt, wie ein clientaktives Remoteobjekt mithilfe eines ActivatedClientTypeEntry Clients registriert wird. Das Beispiel enthält drei Teile, einen Client, einen Server und ein Remoteobjekt, das vom Client und Server verwendet wird.

Das folgende Codebeispiel zeigt einen Client:

#using <System.Runtime.Remoting.dll>
#using <ActivatedClientTypeEntry_Share.dll>

using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
static void main()
{
   // Register TCP Channel.
   ChannelServices::RegisterChannel( gcnew TcpChannel );
   
   // Create activated client type entry.
   ActivatedClientTypeEntry^ activatedClientTypeEntry = gcnew ActivatedClientTypeEntry( HelloServer::typeid, "tcp://localhost:8082" );
   
   // Register type on client to activate it on the server.
   RemotingConfiguration::RegisterActivatedClientType( activatedClientTypeEntry );
   
   // Activate a client activated object type.
   HelloServer^ helloServer = gcnew HelloServer( "ParameterString" );
   
   // Print the object type.
   Console::WriteLine( "Object type of client activated object: {0}", activatedClientTypeEntry->ObjectType->ToString() );
   
   // Print the application URL.
   Console::WriteLine( "Application url where the type is activated: {0}", activatedClientTypeEntry->ApplicationUrl->ToString() );
   
   // Print the string representation of the type entry.
   Console::WriteLine( "Type and assembly name and application URL of the remote object: {0}", activatedClientTypeEntry->ToString() );
   
   // Print a blank line.
   Console::WriteLine();
   
   // Check that server was located.
   if (  !helloServer )
   {
      Console::WriteLine( "Could not locate server" );
   }
   else
   {
      Console::WriteLine( "Calling remote object" );
      Console::WriteLine( helloServer->HelloMethod( "Bill" ) );
   }
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class MyClient

    public static void Main()
    {
        // Register TCP Channel.
        ChannelServices.RegisterChannel(new TcpChannel());

        // Create activated client type entry.
        ActivatedClientTypeEntry myActivatedClientTypeEntry =
            new ActivatedClientTypeEntry(typeof(HelloServer),
            "tcp://localhost:8082");

        // Register type on client to activate it on the server.
        RemotingConfiguration.RegisterActivatedClientType(

        // Activate a client activated object type.
        HelloServer myHelloServer = new HelloServer("ParameterString");

        // Print the object type.
        Console.WriteLine(
            "Object type of client activated object: " +
            myActivatedClientTypeEntry.ObjectType.ToString());

        // Print the application URL.
        Console.WriteLine(
            "Application url where the type is activated: " +
            myActivatedClientTypeEntry.ApplicationUrl);

        // Print the string representation of the type entry.
        Console.WriteLine(
            "Type name, assembly name and application URL " +
            "of the remote object: " +
            myActivatedClientTypeEntry.ToString());

        // Print a blank line.
        Console.WriteLine();

        // Check that server was located.
        if (myHelloServer == null)
        {
            Console.WriteLine("Could not locate server");
        }
        else
        {
            Console.WriteLine("Calling remote object");
            Console.WriteLine(myHelloServer.HelloMethod("Bill"));
        }
    }
}

            Console.WriteLine(myHelloServer.HelloMethod("Bill"))
        End If
    End Sub
End Class

Das folgende Codebeispiel zeigt einen Server für diesen Client:

#using <ActivatedClientTypeEntry_Share.dll>
#using <System.Runtime.Remoting.dll>

using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
void main()
{
   ChannelServices::RegisterChannel( gcnew TcpChannel( 8082 ) );
   RemotingConfiguration::RegisterActivatedServiceType( HelloServer::typeid );
   Console::WriteLine( "Press enter to stop this process" );
   Console::ReadLine();
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class MyServer
{
    public static void Main()
    {
        ChannelServices.RegisterChannel(new TcpChannel(8082));
        RemotingConfiguration.RegisterActivatedServiceType(typeof(HelloServer));
        Console.WriteLine("Press enter to stop this process");
        Console.ReadLine();
   }
}

Imports System.Runtime.Remoting
Imports System.Runtime.Remoting.Channels
Imports System.Runtime.Remoting.Channels.Tcp

Public Class MyServer
    
    Public Shared Sub Main()
        ChannelServices.RegisterChannel(New TcpChannel(8082))
        RemotingConfiguration.RegisterActivatedServiceType(GetType(HelloServer))
        Console.WriteLine("Press enter to stop this process")
        Console.ReadLine()
    End Sub

End Class

Das folgende Codebeispiel stellt das vom Client und dem Server verwendete Remoteobjekt bereit:

using namespace System;
public ref class HelloServer: public MarshalByRefObject
{
public:
   HelloServer( String^ myString )
   {
      Console::WriteLine( "HelloServer activated" );
      Console::WriteLine( "Paramater passed to the constructor is {0}", myString );
   }

   String^ HelloMethod( String^ myName )
   {
      Console::WriteLine( "HelloMethod : {0}", myName );
      return String::Format( "Hi there {0}", myName );
   }

};

using System;
public class HelloServer : MarshalByRefObject
{
    public HelloServer(String myString)
    {
        Console.WriteLine("HelloServer activated");
        Console.WriteLine("Parameter passed to the constructor is "+myString);
    }
    public String HelloMethod(String myName)
    {
        Console.WriteLine("HelloMethod : {0}",myName);
        return "Hi there " + myName;
    }
}

Public Class HelloServer
    Inherits MarshalByRefObject
    
    Public Sub New(myString As String)
        Console.WriteLine("HelloServer activated")
        Console.WriteLine("Parameter passed to the constructor is " + myString)
    End Sub
    
    Public Function HelloMethod(myName As String) As String
        Console.WriteLine("HelloMethod : {0}", myName)
        Return "Hi there " + myName
    End Function 'HelloMethod
End Class

Hinweise

Um eine Instanz eines clientaktivierten Objekts auf dem Client zu erstellen, müssen Sie dessen Type und sie mithilfe der RegisterActivatedClientType Methode auf dem Client registriert werden. Um einen Proxy für eine neue Instanz des clientaktiven Objekts abzurufen, muss der Client zuerst einen Kanal ChannelServices registrieren und dann das Objekt durch Aufrufen newaktivieren.

Um einen clientaktiven Objekttyp mit dem new Schlüsselwort zu aktivieren, müssen Sie zuerst den Objekttyp auf dem Client mithilfe der RegisterActivatedClientType Methode registrieren. Durch Aufrufen RegisterActivatedClientType geben Sie der Remotinginfrastruktur den Standort der Remoteanwendung an, an dem new versucht wird, sie zu erstellen. Wenn Sie andererseits die Activator.CreateInstance Methode verwenden, um eine neue Instanz des clientaktiven Objekts zu erstellen, müssen Sie die URL der Remoteanwendung als Parameter angeben, sodass keine vorherige Registrierung am Clientende erforderlich ist. Um die Activator.CreateInstance Methode mit der URL des Servers anzugeben, auf dem Sie das Objekt erstellen möchten, müssen Sie die URL in einer Instanz der UrlAttribute Klasse kapseln.
