Följande kod visar hur du imperativt använder HttpTransportBindingElement.

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;

    // 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.");

Kommentarer

Klassen HttpTransportBindingElement är startpunkten för att skapa en anpassad bindning som implementerar HTTP-transportprotokollet. HTTP är den primära transporten som används i samverkanssyfte. Den här transporten stöds av Windows Communication Foundation (WCF) för att säkerställa samverkan med andra icke-WCF-webbtjänststackar.

WCF-tjänstmodellen använder den här klassen för att skapa fabriksobjekt som implementerar gränssnitten IChannelFactory och IChannelListener . Dessa fabriksobjekt skapar i sin tur kanaler och lyssnare som överför SOAP-meddelanden med hjälp av HTTP-protokollet.

Du konfigurerar de fabriker som den här klassen skapar genom att ange dess egenskaper, till exempel AuthenticationScheme, HostNameComparisonModeoch MaxBufferSize.

Du kan också ange egenskaper för basklassen, TransportBindingElementtill exempel ManualAddressing, MaxReceivedMessageSizeoch MaxBufferPoolSize. En fullständig lista över egenskaper finns i TransportBindingElement.
