Examples

The following code example demonstrates a simple client using the channel factory to send a message and read the action header from the reply.

using System.Runtime.Serialization;

            //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,

            Message replymessage = channel.Request(requestmessage);
            Console.WriteLine("Reply message received");
            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();
