Sorry, I think this link show not so good code sample. Hard-coded "3" everywhere, why?...

Solution 2

Try List<List<object>> objects;. Obviously object could be any CLR type.

Hope this helps

Correct, my 5.

My 2 cents:
I decided to write 5 lines of real code which would compile immediately as I think OP may have a little problem writing it, assuming little experience.

Please see my answer.

For the OP's reference: to index into a list of lists:
item = listoflists[i][j];

To make a correct answer by Wayne a bit more clear:

C#

using ListOfList =
    System.Collections.Generic.List<
        System.Collections.Generic.List<ListItem>
    >;

class ListItem = {/*...*/}
//or any other type
