OptionalReliableSession.Enabled Propriété

Définition

Espace de noms:

System.ServiceModel

Assembly:

System.ServiceModel.Primitives.dll

Assembly:

System.ServiceModel.dll

Obtient ou définit une valeur indiquant si la session fiable est activée.

public:
 property bool Enabled { bool get(); void set(bool value); };

public bool Enabled { get; set; }

member this.Enabled : bool with get, set

Public Property Enabled As Boolean

Valeur de propriété

Boolean

true si la session fiable est activée ; sinon, false. La valeur par défaut dépend de la liaison qui est utilisée.

Exemples

L'exemple suivant indique comment créer une session fiable, accéder et modifier les valeurs par défaut de cette session.

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

Remarques

La capacité à activer une session fiable est fournie avec trois des liaisons fournies par le système. Une session fiable est :

• Facultative (et désactivée, par défaut) avec NetTcpBinding et WSHttpBinding.

• Requise (et donc activée en permanence) avec WSDualHttpBinding.
