示例

以下示例演示如何创建通道工厂，并使用它来创建和管理通道。

// Construct InstanceContext to handle messages on the callback interface.
// An instance of ChatApp is created and passed to the InstanceContext.
    InstanceContext site = new InstanceContext(new ChatApp());

// Create the participant with the given endpoint configuration.
// Each participant opens a duplex channel to the mesh.
// Participant is an instance of the chat application that has opened a channel to the mesh.

    using (DuplexChannelFactory<IChatChannel> cf =
        new DuplexChannelFactory<IChatChannel>(site,"ChatEndpoint"))
    {
        X509Certificate2 issuer = GetCertificate(
            StoreName.CertificateAuthority,
            StoreLocation.CurrentUser, "CN=" + issuerName,
            X509FindType.FindBySubjectDistinguishedName);
        cf.Credentials.Peer.Certificate =
            GetCertificate(StoreName.My,
            StoreLocation.CurrentUser,
            "CN=" + member,
            X509FindType.FindBySubjectDistinguishedName);
        cf.Credentials.Peer.PeerAuthentication.CertificateValidationMode  =
            X509CertificateValidationMode.Custom;
        cf.Credentials.Peer.PeerAuthentication.CustomCertificateValidator =
            new IssuerBasedValidator();

        using (IChatChannel participant = cf.CreateChannel())
        {
    // Retrieve the PeerNode associated with the participant and register for online/offline events.
    // PeerNode represents a node in the mesh. Mesh is the named collection of connected nodes.
            IOnlineStatus ostat = participant.GetProperty<IOnlineStatus>();
            ostat.Online += new EventHandler(OnOnline);
            ostat.Offline += new EventHandler(OnOffline);

            Console.WriteLine("{0} is ready", member);
            Console.WriteLine("Press <ENTER> to send the chat message.");

    // Announce self to other participants.
            participant.Join(member);
            Console.ReadLine();
            participant.Chat(member, "Hi there - I am chatting");

            Console.WriteLine("Press <ENTER> to terminate this instance of chat.");
            Console.ReadLine();
    // Leave the mesh and close the client.
            participant.Leave(member);
        }
    }

注解

双工通道允许客户端和服务器独立地相互通信，以便两者都可以发起对对方的调用。 双工服务可以将消息发送到客户端终结点，从而提供类似事件的行为。 当客户端与服务建立会话并向服务提供服务时，将发生双工通信，并提供服务可以向其发送消息回客户端的通道。 各种 CreateChannel 方法用于创建这些双工通道。 双工消息模式是 Windows Communication Foundation （WCF） 服务可用的三种消息模式之一。 其他两种消息模式是单向和请求-回复。

有关允许客户端重新连接到服务的双工服务的一般讨论，请参阅 双工服务。 有关使用通道工厂编写 Windows Communication Foundation （WCF） 客户端应用程序所涉及的步骤的概述和讨论，请参阅 如何：使用 ChannelFactory。 有关如何在实现回调接口以访问使用双工消息传送模式的服务的客户端类中创建 Windows Communication Foundation （WCF） 客户端的过程，请参阅 如何：使用双工协定访问服务。
