need to make an instance of object Set

Hello I've got POCO object with two variables of ISet data type and
I need to inicialize this variables to add some data into them (variable1.Add(dataObject)) before I load it to DB.

I thought that I can realize this by NHibernateUtil.Initialize(name of variable/property), but it didn't work.

Thank you very much for you answers. Have a nice day.

I think your problem is that you should be creating the instance of the ISet somewhere in your code, like in the definition of the ISet variable or in the new procedure.

This is what I do:

Code:

private ISet someCollection = new Iesi.Collections.HashedSet();

This works fine with me.

Thank you, but problem is that the hibernate set this property (my ISet property) to NHibernate.Collection.Set type when load it from DB and then when I want to convert this into HashSet type there is Exception "isn't possible to convert NHibernate.Collection.Set to Iesi.Collection.HashSet"

Why do You need to convert it into Iesi.Collection.HashSet?
