How to find if an element of a list is in another list?

Question

I want to know if at least one element in a first list can be found in a second list.

I can see two ways to do it. Let\'s say our lists are:

List<         


        

Answer 1

This is another way to know if an element of one list exists in another list.

bool present = List1.Any(t => List2.Any(y => y == t));
