Examples

The following code example shows a client that uses the channel factory to send a message and read the reply.

            CustomBinding binding = new CustomBinding();
            binding.Elements.Add(new HttpTransportBindingElement());
            //Step2: use the binding to build the channel factory
            IChannelFactory<IRequestChannel> factory =
            binding.BuildChannelFactory<IRequestChannel>(
                             new BindingParameterCollection());
            //open the channel factory
            factory.Open();
            //Step3: use the channel factory to create a channel
            IRequestChannel channel = factory.CreateChannel(
               new EndpointAddress("http://localhost:8080/channelapp"));
            channel.Open();
            //Step4: create a message
            Message requestmessage = Message.CreateMessage(
                MessageVersion.Soap12WSAddressing10,

            Console.WriteLine("Reply action: {0}",
                                  replymessage.Headers.Action);

            //don't forget to close the factory
            factory.Close();
        }

            Console.WriteLine("Press [ENTER] to exit");
            Console.ReadLine();

Remarks

After a message is created, the message body can be read using the GetBody methods on the returned message. The returned object encapsulates all the child elements within the Body element. Because the body of a message is a stream, it can only be written once, or read once.

Use the GetBody<T>(XmlObjectSerializer) overload when working with JSON messages; the GetBody<T>() overload does not work.

public:
generic <typename T>
 T GetBody();

public T GetBody<T> ();

member this.GetBody : unit -> 'T

Public Function GetBody(Of T) () As T

public:
generic <typename T>
 T GetBody(System::Runtime::Serialization::XmlObjectSerializer ^ serializer);

public T GetBody<T> (System.Runtime.Serialization.XmlObjectSerializer serializer);

member this.GetBody : System.Runtime.Serialization.XmlObjectSerializer -> 'T

Public Function GetBody(Of T) (serializer As XmlObjectSerializer) As T
