ChannelFactory<TChannel> 类

一个创建不同类型通道的工厂，客户端使用这些通道将消息发送到不同配置的服务终结点。

命名空间:   System.ServiceModel

语法

public class ChannelFactory<TChannel> : ChannelFactory, IChannelFactory<TChannel>,

    IChannelFactory, ICommunicationObject

类型参数

TChannel

由通道工厂生成的通道类型。 此类型必须为 IOutputChannel 或 IRequestChannel。

备注

使用此泛型类可实现一些更高级的方案，在这些方案中有创建通道工厂（可用于创建多个通道类型）的要求。

以编程方式添加行为时，可以在创建任何通道之前将行为添加到 Behaviors 上相应的 ChannelFactory 属性。 有关代码示例，请参见“示例”部分。

/// 下面的示例演示如何创建通道工厂并用它来创建和管理通道

public static void Main()

{

    BasicHttpBinding binding = new BasicHttpBinding();

    EndpointAddress address = new EndpointAddress("http://localhost:8000/ChannelApp");

    ChannelFactory<IRequestChannel> factory = new ChannelFactory<IRequestChannel>(binding, address);

    IRequestChannel channel = factory.CreateChannel();

    channel.Open();

    Message request = Message.CreateMessage(MessageVersion.Soap11, "hello");

    Message reply = channel.Request(request);

    Console.Out.WriteLine(reply.Headers.Action);

    reply.Close();

    channel.Close();

    factory.Close();

}

      Console.WriteLine("Press ENTER to exit:");

      Console.ReadLine();

      // Done with service.
