Can I not load a given mapped property (nhibernate)?

Question

I am using WCF for my project and i need to transit some entities through it.

The thing is that some of them have lists inside, with an enormeous ammount of items, and so forth, i cannot pass it through WCF, given its size.

How can I, through code, not load a given property from the database, but load all the rest?

Are you certain that size is the reason you can't transmit the lists? I've seen others have trouble with nHibernate because it uses the `IList` interface for lists. — John Saunders, Jul 30 '09 at 00:01

By default the NH lists are lazy loaded - so unless you specified otherwise, the list will not be loaded.

However , the property will be an IProxy..something that won't be serializable. If you want you can probably set an [XmlIgnore] or [NotSerializable] (not sure how it's sent over wcf) on that specific property.

Having said that - do prefer using a DTO instead of sending your entity over the wire. See this for more about why you shouldn't send the entity.
