Edit Question
Title
Body
I have two collections which have property Email in both collections. I need to get a list of the items in the first list where Email does not exist in the second list. With SQL I would just use "not in", but I do not know the equivalent in LINQ. How is that done? So far I have a join, like... var matches = from item1 in list1 join item2 in list2 on item1.Email equals item2.Email select new { Email = list1.Email }; But I cannot join since I need the difference and the join would fail. I need some way of using Contains or Exists I believe. I just have not found an example to do that yet.
