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>();
