c# - migrating to dbcontext LINQ where clause string parameter -

i'm migrating project objectcontext dbcontext , have problem sentence:

var query = db.inventory.where("it.idstate in {" + states + "}");

this works objectcontext error @ compilation time:

error   cs1503  argument 2: cannot convert 'string' 'system.linq.expressions.expression<system.func<test.dal.inventory, bool>>'

seems not posible now, tryied expose objectcontext it, couldn't find way

any idea? thank!

you can (and should) type these arguments expression.

var query = db.inventory.where(x => states.contains(x.idstate));
