I would create a QueryOver like this
SELECT *
FROM Table
WHERE Field IN (1,2,3,4,5)
I've tried with Contains
method but I've encountered the Exception
"System.Exception: Unrecognised method call: System.String:Boolean Contains(System.String)"
Here my code
var qOver = _HibSession.QueryOver<MyModel>(() => baseModel)
.JoinAlias(() => baseModel.Submodels, () => subModels)
.Where(() => subModels.ID.Contains(IDsSubModels))
.List<MyModel>();

I've found the solution!! :-)
var qOver = _HibSession.QueryOver<MyModel>(() => baseModel)
.JoinAlias(() => baseModel.Submodels, () => subModels)
.WhereRestrictionOn(() => subModels.ID).IsIn(IDsSubModels)
.List<MyModel>();

You can try something like this:
// if IDsSubModels - array of IDs
var qOver = _HibSession.QueryOver<MyModel>()
.Where(x => x.ID.IsIn(IDsSubModels))
You don't need a join in this situation
This works and is more elegant
var Strings = new List<string> { "string1", "string2" };
var value = _currentSession
.QueryOver<T>()
.Where(x => x.TProperty == value)
.And(Restrictions.On<T>(y=>y.TProperty).IsIn(Strings))
.OrderBy(x => x.TProperty).Desc.SingleOrDefault();
where T is a Class and TProperty is a property of T
