NHibernate using QueryOver with WHERE IN

Question

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>();

Answer 1

I've found the solution!! :-)

var qOver = _HibSession.QueryOver<MyModel>(() => baseModel)
    .JoinAlias(() => baseModel.Submodels, () => subModels)
    .WhereRestrictionOn(() => subModels.ID).IsIn(IDsSubModels)
    .List<MyModel>();

Answer 2

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

Answer 3

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
