Definition

Achtung

This Remoting API is not supported and throws PlatformNotSupportedException.

Ruft ein Lebensdauerdienstobjekt zur Steuerung der Lebensdauerrichtlinie für diese Instanz ab.Obtains a lifetime service object to control the lifetime policy for this instance.

Gibt zurück

Object

Ein Objekt vom Typ ILease, das zur Steuerung der Lebensdauerrichtlinien für diese Instanz verwendet wird.An object of type ILease used to control the lifetime policy for this instance. Dies ist das aktuelle Lebensdauerdienstobjekt für diese Instanz, sofern vorhanden, bzw. ein neues Lebensdauerdienstobjekt, das mit dem Wert der LeaseManagerPollTime-Eigenschaft initialisiert wurde.This is the current lifetime service object for this instance if one exists; otherwise, a new lifetime service object initialized to the value of the LeaseManagerPollTime property.

Attribute

Ausnahmen

Der direkte Aufrufer verfügt nicht über die Berechtigung für die Infrastruktur.The immediate caller does not have infrastructure permission.

Nur .NET Core und .NET 5 und höher: In allen Fällen..NET Core and .NET 5+ only: In all cases.

Beispiele

Im folgenden Codebeispiel wird das Erstellen einer Lease veranschaulicht.The following code example demonstrates creating a lease.

public ref class MyClass: public MarshalByRefObject
{
public:
   
   [System::Security::Permissions::SecurityPermissionAttribute
   (System::Security::Permissions::SecurityAction::Demand,
   Flags=System::Security::Permissions::SecurityPermissionFlag::Infrastructure)]
   virtual Object^ InitializeLifetimeService() override
   {
      ILease^ lease = dynamic_cast<ILease^>(MarshalByRefObject::InitializeLifetimeService());
      if ( lease->CurrentState == LeaseState::Initial )
      {
         lease->InitialLeaseTime = TimeSpan::FromMinutes( 1 );
         lease->SponsorshipTimeout = TimeSpan::FromMinutes( 2 );
         lease->RenewOnCallTime = TimeSpan::FromSeconds( 2 );
      }

      return lease;
   }

};

public class MyClass : MarshalByRefObject
{
  [SecurityPermissionAttribute(SecurityAction.Demand,
                               Flags=SecurityPermissionFlag.Infrastructure)]
  public override Object InitializeLifetimeService()
  {
    ILease lease = (ILease)base.InitializeLifetimeService();
    if (lease.CurrentState == LeaseState.Initial)
    {
         lease.InitialLeaseTime = TimeSpan.FromMinutes(1);
         lease.SponsorshipTimeout = TimeSpan.FromMinutes(2);
          lease.RenewOnCallTime = TimeSpan.FromSeconds(2);
    }
      return lease;
  }
}

    Public Overrides Function InitializeLifetimeService() As Object
        Dim lease As ILease = CType(MyBase.InitializeLifetimeService(), ILease)
        If lease.CurrentState = LeaseState.Initial Then
            lease.InitialLeaseTime = TimeSpan.FromMinutes(1)
            lease.SponsorshipTimeout = TimeSpan.FromMinutes(2)
            lease.RenewOnCallTime = TimeSpan.FromSeconds(2)
