Examples

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

using System.Runtime.Serialization;

namespace ConsoleApplication1

    {

        static void RunClient()
        {
            //Step1: create a binding with just HTTP
            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,
                "http://contoso.com/someaction",
                 "This is the body data");
            //send message
            Message replymessage = channel.Request(requestmessage);
            Console.WriteLine("Reply message received");
            Console.WriteLine("Reply action: {0}",
                                  replymessage.Headers.Action);
            string data = replymessage.GetBody<string>();
            Console.WriteLine("Reply content: {0}", data);
            //Step5: don't forget to close the message
            requestmessage.Close();
            replymessage.Close();
            //don't forget to close the channel
            channel.Close();
            //don't forget to close the factory
            factory.Close();
        }
        public static void Main()
        {
            Console.WriteLine("Press [ENTER] when service is ready");
            Console.ReadLine();
            RunClient();
            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.

GetBody<T>()

Source:

Message.cs

Retrieves the body of this Message instance.

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

public T GetBody<T> ();

member this.GetBody : unit -> 'T

Public Function GetBody(Of T) () As T

Type Parameters

T

The body of the message.

Returns

T

An object of type T that contains the body of this message.

Remarks

A Message instance has a body that corresponds to the SOAP body. It can be accessed as an XmlDictionaryReader by calling GetReaderAtBodyContents. It is initially positioned directly after the <S:Body> element, and it returns EOF on reaching the </S:Body> element. Alternatively, if you expect the body to contain a serialized object, you can call GetBody instead. You should be aware that a message body can only be accessed once and a message can only be written once. If you want to access the Body multiple times, use CreateBufferedCopy to create a MessageBuffer instance.

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

GetBody<T>(XmlObjectSerializer)

Source:

Message.cs

Retrieves the body of this Message using the specified serializer.

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

Type Parameters

T

The body of the message.

Parameters

serializer

XmlObjectSerializer

A XmlObjectSerializer object used to read the body of the message.

Returns

T

An object of type T that contains the body of this message.

Exceptions

ArgumentNullException

serializer is null.
