You’ve mostly seen LINQ used with arrays, but it can be used for lists as well! The syntax is the same:

List<string> heroesList = new List<string> { "D. Va", "Lucio", "Soldier 76" };

var longLoudheroes = from h in heroesList
  where h.Length > 6
  select h.ToUpper();

// longLoudHeroes is [ "SOLDIER 76" ]

Technically, LINQ can be used with any type that supports foreach loops, but we won’t cover all of those here.
