Exemplos

Pode ReliableSessionBindingElement ser adicionado a qualquer associação personalizada. Isso é feito usando os seguintes elementos de configuração.

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

O código de exemplo a seguir demonstra como usar ReliableSessionBindingElement no código.

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

Comentários

Fornece sessões e, opcionalmente, fornece entrega de mensagens ordenadas. Essa sessão implementada pode cruzar os intermediários soap e de transporte.

Cada elemento de associação representa uma etapa de processamento ao enviar ou receber mensagens. No runtime, os elementos de associação criam as fábricas de canais e os ouvintes necessários para criar pilhas de canal de saída e de entrada necessárias para enviar e receber mensagens. Ele ReliableSessionBindingElement fornece uma camada opcional na pilha que pode estabelecer uma sessão confiável entre pontos de extremidade e configurar o comportamento desta sessão.

As ReliableSessionBindingElement associações padrão são fornecidas na tabela a seguir.
