Query partial properties of an object in NHibernate

We can use the classes in the NHibernate.Transform namespace to get partial properties of an object.

 

var rs  =   this .CurrentSession.CreateCriteria < IDiamond > ()
    .CreateAlias( " Vendor " ,  " Vendor " )
    .SetProjection( global ::NHibernate.Criterion.Projections.ProjectionList()
        .Add( global ::NHibernate.Criterion.Projections.Property( " Id " ),  " Id " )
        .Add( global ::NHibernate.Criterion.Projections.Property( " StockNumber " ),  " StockNumber " )
        .Add( global ::NHibernate.Criterion.Projections.Property( " Vendor.Name " ),  " VendorName " ))
    .SetResultTransformer( global ::NHibernate.Transform.Transformers.AliasToBean < TestResult > ())
    .List < TestResult > ();
