MS CRM 2011 - While clonning how to get associated records when we have 1:N relationship.

MS CRM 2011 - While clonning how to get associated records when we have 1:N relationship. I have used following code for N:N relationship, by using http://social.msdn.microsoft.com/Forums/en-US/crmdevelopment/thread/96b2c525-b4b2-4768-b9d8-c4a6aac9eb21

Can any one suggest on code changes when 1:N relationship is used.

privatevoidCopyClonedRecords(Entity account)
        {
            EntityReference clonedAccount=(EntityReference)account["new_clonedaccountid"];
            if(clonedAccount !=null&& clonedAccount.Id!=default(Guid))//if no cloned account id, it's not a clone
            {
               List<Guid> contactIds=GetAssociatedContactIds(clonedAccount.Id);
               if(contactIds.Count>0)
               {
                    service.Execute(newAssociateRequest
                   {
                       Relationship=newRelationship("new_account_contact"),
                       Target=newEntityReference("account", account.Id),
                       RelatedEntities=newEntityReferenceCollection(contactIds.Select(a=>newEntityReference("contact", a)).ToList())
                   });
               }
            }
        }

        privateList<Guid>GetAssociatedContactIds(Guid accountId)
        {
            List<Guid> contactIds=newList<Guid>();

            QueryExpression qe=newQueryExpression("contact");

            LinkEntity link1=newLinkEntity
            {
               LinkFromEntityName="contact",
               LinkToEntityName="new_account_contact",
               LinkFromAttributeName="contactid",
               LinkToAttributeName="contactid"
            };

            qe.LinkEntities.Add(link1);

            LinkEntity link2=newLinkEntity
            {
               LinkFromEntityName="new_account_contact",
               LinkToEntityName="account",
               LinkFromAttributeName="accountid",
               LinkToAttributeName="accountid"
            };

            link2.LinkCriteria.AddCondition("accountid",ConditionOperator.Equal, accountId);
            link1.LinkEntities.Add(link2);

            EntityCollection collection= service.RetrieveMultiple(qe);
            if(collection !=null&& collection.Entities!=null&& collection.Entities.Count>0)
            {
                contactIds= collection.Entities.Select(a=> a.Id).ToList();
            }

            return contactIds;
        }
