Vorgehensweise: Verwenden der ChannelFactoryHow to: Use the ChannelFactory

Die generische ChannelFactory<TChannel>-Klasse wird in komplexen Szenarien verwendet, in denen eine Kanalfactory erstellt werden muss, die zum Erstellen mehrerer Kanäle eingesetzt werden kann.The generic ChannelFactory<TChannel> class is used in advanced scenarios that require the creation of a channel factory that can be used to create more than one channel.

So erstellen und verwenden Sie die ChannelFactory-KlasseTo create and use the ChannelFactory class

  1. Erstellen Sie und führen Sie einen Windows Communication Foundation (WCF)-Dienst.Build and run an Windows Communication Foundation (WCF) service. Weitere Informationen finden Sie unter entwerfen und Implementieren von Diensten, Konfigurieren von Services, und Hostingdienste.For more information, see Designing and Implementing Services, Configuring Services, and Hosting Services.

  2. Verwenden der ServiceModel Metadata Utility Tool (Svcutil.exe) zum Generieren des Vertrags (Schnittstelle) für den Client.Use the ServiceModel Metadata Utility Tool (Svcutil.exe) to generate the contract (interface) for the client.

  3. Verwenden Sie im Clientcode die ChannelFactory<TChannel>-Klasse, um mehrere Endpunktlistener zu erstellen.In the client code, use the ChannelFactory<TChannel> class to create multiple endpoint listeners.

// This code generated by svcutil.exe.
[ServiceContract()]
interface IMath
{
    [OperationContract()]
     double Add(double A, double B);
}

public class Math : IMath
{
    public double Add(double A, double B) 
    {
        return A + B;
    }
}

public sealed class Test
{
    static void Main()
    {
        // Code not shown.
    }

    public void Run()
    {
        // This code is written by an application developer.
        // Create a channel factory.
        BasicHttpBinding myBinding = new BasicHttpBinding();
	
        EndpointAddress myEndpoint = new EndpointAddress("http://localhost/MathService/Ep1");

        ChannelFactory<IMath> myChannelFactory = new ChannelFactory<IMath>(myBinding, myEndpoint);

        // Create a channel.
        IMath wcfClient1 = myChannelFactory.CreateChannel();
        double s = wcfClient1.Add(3, 39);
        Console.WriteLine(s.ToString());
	((IClientChannel)wcfClient1).Close();

        // Create another channel.
        IMath wcfClient2 = myChannelFactory.CreateChannel();
        s = wcfClient2.Add(15, 27);
        Console.WriteLine(s.ToString());
	((IClientChannel)wcfClient2).Close();
	myChannelFactory.Close();
    }
