LINQ: Select where object does not contain items from list

Question

I\'m struggling with LINQ syntax here...thought I\'d toss it out here. I cant find exactly what I\'m looking for anywhere else.

OK, say I\'ve got this:

Answer 1

dump this into a more specific collection of just the ids you don't want

var notTheseBarIds = filterBars.Select(fb => fb.BarId);

then try this:

fooSelect = (from f in fooBunch
             where !notTheseBarIds.Contains(f.BarId)
             select f).ToList();

or this:

fooSelect = fooBunch.Where(f => !notTheseBarIds.Contains(f.BarId)).ToList();
