Are 2 dimensional Lists possible in c#?

Question

I\'d like to set up a multidimensional list. For reference, I am working on a playlist analyzer.

I have a file/file-list, which my program saves in a standard list.

Answer 1

I used:

List> List1 = new List>
var List = new List();
List.add("Test");
List.add("Test2");
List1.add(List);
var List = new List();
List.add("Test3");
List1.add(List);

that equals:

List1
(
[0] => List2 // List1[0][x]
    (
        [0] => Test  // List[0][0] etc.
        [1] => Test2

    )
[1] => List2
    (
        [0] => Test3
