Voorbeelden

De ReliableSessionBindingElement kan worden toegevoegd aan elke aangepaste binding. Dit gebeurt met behulp van de volgende configuratie-elementen.

<bindings>
    <customBinding>
        <binding configurationName="ReliabilityHTTP">
            <reliableSession/>
        </binding>
    </customBinding>
</bindings>

In de volgende voorbeeldcode ziet u hoe u deze kunt gebruiken ReliableSessionBindingElement in code.

Uri baseAddress = new Uri("http://localhost:8000/servicemodelsamples/service");

// Create a ServiceHost for the CalculatorService type and provide the base address.
using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress))
{
    // Create a custom binding that contains two binding elements.
    ReliableSessionBindingElement reliableSession = new ReliableSessionBindingElement();
    reliableSession.Ordered = true;

    HttpTransportBindingElement httpTransport = new HttpTransportBindingElement();
    httpTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous;
    httpTransport.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;

    CustomBinding binding = new CustomBinding(reliableSession, httpTransport);

    // Add an endpoint using that binding.
    serviceHost.AddServiceEndpoint(typeof(ICalculator), binding, "");

    // Add a MEX endpoint.
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.HttpGetUrl = new Uri("http://localhost:8001/servicemodelsamples");
    serviceHost.Description.Behaviors.Add(smb);

    // Open the ServiceHostBase to create listeners and start listening for messages.
    serviceHost.Open();

    // The service can now be accessed.
    Console.WriteLine("The service is ready.");
    Console.WriteLine("Press <ENTER> to terminate service.");
    Console.WriteLine();
    Console.ReadLine();

    // Close the ServiceHostBase to shutdown the service.
    serviceHost.Close();
}

Dim baseAddress As New Uri("http://localhost:8000/servicemodelsamples/service")

' Create a ServiceHost for the CalculatorService type and provide the base address.
Using serviceHost As New ServiceHost(GetType(CalculatorService), baseAddress)
    ' Create a custom binding that contains two binding elements.
    Dim reliableSession As New ReliableSessionBindingElement()
    reliableSession.Ordered = True

    Dim httpTransport As New HttpTransportBindingElement()
    httpTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous
    httpTransport.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard

    Dim binding As New CustomBinding(reliableSession, httpTransport)

    ' Add an endpoint using that binding.
    serviceHost.AddServiceEndpoint(GetType(ICalculator), binding, "")

    ' Add a MEX endpoint.
    Dim smb As New ServiceMetadataBehavior()
    smb.HttpGetEnabled = True
    smb.HttpGetUrl = New Uri("http://localhost:8001/servicemodelsamples")
    serviceHost.Description.Behaviors.Add(smb)

    ' Open the ServiceHostBase to create listeners and start listening for messages.
    serviceHost.Open()

    ' The service can now be accessed.
    Console.WriteLine("The service is ready.")
    Console.WriteLine("Press <ENTER> to terminate service.")
    Console.WriteLine()
    Console.ReadLine()

    ' Close the ServiceHostBase to shutdown the service.
    serviceHost.Close()
End Using

Opmerkingen

Biedt sessies en biedt desgewenst bestelde berichtbezorging. Deze geïmplementeerde sessie kan SOAP- en transporttussenpersonen kruisen.

Elk bindingselement vertegenwoordigt een verwerkingsstap bij het verzenden of ontvangen van berichten. Tijdens runtime maken bindingselementen de kanaalfactory's en listeners die nodig zijn om uitgaande en binnenkomende kanaalstacks te bouwen die nodig zijn voor het verzenden en ontvangen van berichten. De ReliableSessionBindingElement biedt een optionele laag in de stack waarmee een betrouwbare sessie tussen eindpunten tot stand kan worden gebracht en het gedrag van deze sessie kan worden geconfigureerd.

De ReliableSessionBindingElement tabel bevat de standaardbindingen in de volgende tabel.
