Public Overridable Function InitializeLifetimeService () As Object

Returns

Object

An object of type ILease used to control the lifetime policy for this instance. 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.

Examples

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;
  }
}
