How to clone objects in NHibernate?

Question

How to implement cloning of objects (entities) in NHibernate? In the classes of entities has properties such

public virtual IList<Club> Clubs { get; set; }

All classes are inherited from BaseObject. I tried to implement using xml serialization, but the interfaces are not serialized.

Thank you for your answers!

Answer 1

Cloning of entities is not in the NHIbernate scope. You should implement this. Here is a good example how.

Answer 2

Use DTOs.

Answer 3

I don't know of your domain or requirements, nor whether am I misunderstanding your need, but implementing the ICloneable interface and writing the code to clone your object should work.

Remember you'll have to type cast when cloning.

ClonedObject clonedObjectinstance = (ClonedObject)initialEntityInstance.Clone();

Answer 4

AutoMapper http://automapper.codeplex.com/ resolved my question. An example of cloning a business object:

Mapper.CreateMap<Transaction, Transaction>();
var newtransact = new Transaction();
Mapper.Map(transact, newtransact);
