c# - linq - order by who has been selected -

i wondering how orderby has been selected in list in linq.

for example, have 4 names in list

bob sue ryan sarah

just numbers beside them associated id.

so user selects "sue , sarah" - want sue , sarah on top of list

2 - sue 4 - sarah 1 - bob 3 - ryan

the linq have is

list<entity> = list.orderby(x => x.id == idsselected).groupby() // not grouping by...

any ideas?

thanks in advance

you can utilize orderby bool have utilize orderbydescending if trues should on top of list( remember treating true 1 , false 0):

list<entity> = list .orderbydescending(x => idsselected.contains(x.id)) .thenby(x => x.name) // if desired .tolist();
