Question

I have a simple set of tables…

List
– Id

Items
– Id

Entries
– EntryId
– ListId
– ItemId

I’m trying to design a Linq query that will take a given ListId and return all of the Items that do not have an Entry with that ListId on it. It sounds pretty simple, but it keeps coming up wrong. Any ideas?

If you want to select all Items you could do something like this.

var x = Items.Where(item => !Entries.Any(entry => entry.ItemID == item.ID && entry.ListID == listID));
