C# - Two lists linked with the same value

Question

In script A, I have a generic list:

 public List<int> firstList = new List<int>();

In script B, I have a second list:

 public List<int> secondList = new List<int>();

I then do this:

 scriptB.secondList = firstList;

Whenever I change firstList, secondList gets changed too, and vice versa. I don't want this to happen. What am I missing?

You have to make a new list, but you are referencing an existing one

Try:

 scriptB.secondList = new List<int>(firstList);

Thank you! Turns out I'm a C# newbie :) I'm used to other languages where assignment is by value.
