Exemples
L'exemple de code suivant illustre un client simple qui utilise la fabrication de canal pour envoyer un message et lire l'en-tête d'action dans la réponse.
using System;
using System.Collections.Generic;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.Runtime.Serialization;
namespace ConsoleApplication1
{
class client
{
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();
