Entity Framework 4 / Linq: How to OrderBy() a hierarchical Entity? -

-

i have viewmodel carved several entity relations:

products[].prices[].others[].myfield

how order products[] nested myfield? when clause, it's this:

products.where( p => p.prices.any( q => q.others.any( r => r.myfield == 4)));

so if wanted products.orderby() , order myfield, expression like?

products.orderby( p => p.prices.selectmany( ??

as have several prices below product need select 1 sort on, like

products.orderby( p => p.prices.first().others.first().myfield )

or if want order highest price

products.orderby( p => p.prices.orderbydescending(price => price.value).first().others.first().myfield )
