Question

I have a table called Tag with a column called Label and a column called AuctionId. I also have an array of strings which are search terms. I want to write some Linq to Entities code which will give me a distinct list of AuctionIds where the the Label matches one of the search terms. Here is the pseudocode for this:

return a list of unique AuctionIds where Label is in searchTerms

How can this be done?

Answer 1

You can use Contains() on the list.

List<String> AuctionIDs = (from tagItem in Tags
                           where searchItems.Contains(tagItem.Label)
                           select tagItem.AutionID).Distinct().ToList();
