Esempio

Nell'esempio seguente viene illustrato come creare una nuova sessione affidabile, accedere e modificare i valori predefiniti di tale sessione.

private void Run()
{
    WSHttpBinding b = new WSHttpBinding();
    b.Name = "HttpOrderedReliableSessionBinding";

    // Get a reference to the OptionalreliableSession object of the
    // binding and set its properties to new values.
    OptionalReliableSession myReliableSession = b.ReliableSession;
    myReliableSession.Enabled = true; // The default is false.
    myReliableSession.Ordered = false; // The default is true.
    myReliableSession.InactivityTimeout =
        new TimeSpan(0, 15, 0); // The default is 10 minutes.
    // Create a URI for the service's base address.
    Uri baseAddress = new Uri("http://localhost:8008/Calculator");

    // Create a service host.
    ServiceHost sh = new ServiceHost(typeof(Calculator), baseAddress);

    // Optional: Print out the binding information.
    PrintBindingInfo(b);
    // Create a URI for an endpoint, then add a service endpoint using the
    // binding with the latered OptionalReliableSession settings.
    sh.AddServiceEndpoint(typeof(ICalculator), b, "ReliableCalculator");
    sh.Open();

    Console.WriteLine("Listening...");
    Console.ReadLine();
    sh.Close();
}

private void PrintBindingInfo(WSHttpBinding b)
{
    Console.WriteLine(b.Name);
    Console.WriteLine("Enabled: {0}", b.ReliableSession.Enabled);
    Console.WriteLine("Ordered: {0}", b.ReliableSession.Ordered);
    Console.WriteLine("Inactivity in Minutes: {0}",
        b.ReliableSession.InactivityTimeout.TotalMinutes);
}

Private Sub Run()
    Dim b As New WSHttpBinding()
    b.Name = "HttpOrderedReliableSessionBinding"

    ' Get a reference to the OptionalreliableSession object of the 
    ' binding and set its properties to new values.
    Dim myReliableSession As OptionalReliableSession = b.ReliableSession
    myReliableSession.Enabled = True ' The default is false.
    myReliableSession.Ordered = False ' The default is true. 
    myReliableSession.InactivityTimeout = New TimeSpan(0, 15, 0)
    ' The default is 10 minutes.
    ' Create a URI for the service's base address.
    Dim baseAddress As New Uri("http://localhost:8008/Calculator")

    ' Create a service host.
    Dim sh As New ServiceHost(GetType(Calculator), baseAddress)

    ' Optional: Print out the binding information. 
    PrintBindingInfo(b)
    ' Create a URI for an endpoint, then add a service endpoint using the
    ' binding with the latered OptionalReliableSession settings.
    sh.AddServiceEndpoint(GetType(ICalculator), b, "ReliableCalculator")
    sh.Open()

    Console.WriteLine("Listening...")
    Console.ReadLine()
    sh.Close()
End Sub

Private Sub PrintBindingInfo(ByVal b As WSHttpBinding)
    Console.WriteLine(b.Name)
    Console.WriteLine("Enabled: {0}", b.ReliableSession.Enabled)
    Console.WriteLine("Ordered: {0}", b.ReliableSession.Ordered)
    Console.WriteLine("Inactivity in Minutes: {0}", b.ReliableSession.InactivityTimeout.TotalMinutes)

End Sub

Commenti

La possibilità di abilitare una sessione affidabile viene fornita con tre delle associazioni fornite dal sistema. Una sessione affidabile è:

• Facoltativo (e disattivato per impostazione predefinita) con NetTcpBinding e e WSHttpBinding

• Obbligatorio (e quindi sempre attivo) con WSDualHttpBinding.
