Attention

This Remoting API is not supported and throws PlatformNotSupportedException.

Obtient un objet de service de durée de vie pour contrôler la stratégie de durée de vie de cette instance.

Retours

Object

Objet de type ILease utilisé pour contrôler la stratégie de durée de vie de cette instance. Il s’agit de l’objet de service de durée de vie actuel pour cette instance s’il en existe un ; sinon, un nouvel objet de service de durée de vie initialisé à la valeur de la LeaseManagerPollTime propriété.

Attributs
ObsoleteAttribute SecurityCriticalAttribute

Exceptions

SecurityException

L’appelant immédiat n’a pas d’autorisation d’infrastructure.

PlatformNotSupportedException

.NET Core et .NET 5+ uniquement : dans tous les cas.

Exemples

L’exemple de code suivant illustre la création d’un bail.

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

  public override Object InitializeLifetimeService()
