.net - How to convert to a strong type that has a collection? -

i'm trying convert entity contains collections model can't figure out how include collections in model.

for simple example of this, please see model below:

namespace models      public class productmodel         public property id integer         public property description string         public property isinstock boolean         public property orders list(of productordermodel)      end class      public class productordermodel         public property id integer         public property orderdate datetime         public property delivereddate datetime?         public property shippingaddress string     end class  end namespace 

now can cast product model shown below:

dim simplifiedproductmodel productmodel =     p in dc.products _     select new productmodel { _         .id = p.productid, _         .description = p.productdescription, _         .isinstock = p.productisinstock, _         .ordercount = p.orders.count() _         } 

what can't figure out how include collection using simplified model well.

dim simplifiedproductmodel productmodel =     p in dc.products _     select new productmodel { _     .id = p.productid, _     .description = p.productdescription, _     .isinstock = p.productisinstock, _     .ordercount = p.orders.count(), _     .orders = p.orders.???? ===> new productordermodel          {              .id = ???? o.orderid ,              .orderdate = ???? o.createdate,              etc.               } 

like this?

dim simplifiedproductmodel productmodel = p in dc.products _                                         select new productmodel { _                                         .id = p.productid, _                                         .description = p.productdescription, _                                         .isinstock = p.productisinstock, _                                         .ordercount = p.orders.count(), _                                         .orders = p.orders.select( _                                             function(o) new productordermodel _                                                 { _                                                     .id = o.orderid , _                                                     .orderdate = o.createdate, _                                                     etc.                                                   }                                             )                                          }
