How do I retrieve items from a List<T> where one property contains exactly the words from another list?

Question

I am trying to retrieve only the items from a List<T> where one of the properties contains the words from another list.

Once it works I will use the code on my actual database, but the below is basically what I want to do.

List<string> WordsList = new List<string>();

WordsList.Add("THIS");
WordsList.Add("CAT");

List<Sentence> SentencesList = new List<Sentence>();

SentencesList.Add(new Sentence { Description = "THIS SENTENCE CONTAINS THE WORD DOG" });
SentencesList.Add(new Sentence { Description = "THIS SENTENCE CONTAINS THE WORD CAT" });
SentencesList.Add(new Sentence { Description = "THIS SENTENCE CONTAINS THE WORD DOG AND THE WORD CAT" });
SentencesList.Add(new Sentence { Description = "THIS SENTENCE CONTAINS NEITHER" });

Now I want to get the items from SentencesList that contain only the words "THIS" and "CAT "

var records = SentencesList.Where(x => WordsList.Any(y => x.Description.Contains(y))).ToList();

The above piece of code retrieves all items because they contain "THIS" or "CAT"

Answer 1

If you want to change or into and logic, all you have to do is to change WordsList.Any into WordsList.All condition:

 var records = SentencesList
   .Where(x => WordsList.All(y => x.Description.Contains(y)))
   .ToList(); 

Now we want all words in WordsList to be in x
