I am trying to figure out the best approach to go about solving this "listArray-assignment" problem. I am opening a txt file (examples of lines in file provided below) and reading it with File.ReadAllLines. From there, I add all of the actors to listBox1 (while avoiding the addition of duplicate names).

That's the easy part; Here's the kicker: the txt file has movies associated with the actors. These movies must appear in listBox2 when the actor in these movies is selected in listBox1. Many actors, indeed, have multiple movies (refer to so I want to set up a 2D array that stores the first list as the actor list and the second list as the movie list, where the movies are assigned to their respective actors.

To clarify, if "John" has the movies "a" "b" and "c" then John should be an element in list 1. List 2 (corresponding with "John") should be assigned to values a, b, and c (since they are John's movies).

My two ideas were 1) a List and 2) a List> but my attempts to fill these lists were ineffective.

If you understand how to solve this, I would greatly appreciate you weighing in:)

Let me know if either of my approaches would be effective (and how to implement them) or if I need to change my approach entirely. Thank you!!
