How to return id from NHibernate ISession.SaveOrUpdate

I am using ISession.SaveOrUpdate to insert new objects and updaet existing.

If I use ISession.Save(..) this returns the identity of the inserted record.

For SaveOrUpdate I am doing the following:

   public int Save(Vehicle entity) {
        using (var txn = _session.BeginTransaction()) {
            _session.SaveOrUpdate(entity);
            txn.Commit();
        }
        return entity.Id;
    }

Is this the best way to return my identity?

Thanks,

Ben

There's nothing wrong with that. But since the identity is set on the object, why not make the method return void:

   public void Save(Vehicle entity) {
    using (var txn = _session.BeginTransaction()) {
        _session.SaveOrUpdate(entity);
        txn.Commit();
    }
}
