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

Here is how to make a 2 dimensional list

        // Generating lists in a loop.
        List> biglist = new List>();

        for(int i = 1; i <= 10; i++)
        {
            List list1 = new List();
            biglist.Add(list1);
        }

        // Populating the lists
        for (int i = 0; i < 10; i++)
        {
            for(int j = 0; j < 10; j++)
            {
                biglist[i].Add((i).ToString() + " " + j.ToString());
            }
        }

        textbox1.Text = biglist[5][9] + "\n";

Be aware of the danger of accessing a location that is not populated.
