Question

Is it possible to create a multidimensional arraylist in C#?

StartDate   Qty   size
9/1/2010    10     15
9/1/2009    12     17
9/1/2008    11     19

StartDate, Qty and size are the 3 arraylists. I need to have them in a single arraylist. I would also need to sort this arraylist by StartDate. Is this possible? Is there a better way to do it other than arraylist?

Answer 1

You can do it that way, yes. But in this case since each row seems related, why not create a class to hold the data:

public class Info
{
    public DateTime StartDate { get; set; }
    public int Qty { get; set; }
    public int Size { get; set; }
}

And then just have a regular List to hold the objects:

List<Info> infoList = new List<Info>();

That will save you from having to worry about the ordering of each List. To handle the ordering, you can use the LINQ to Objects Extension methods:

var sortedList = infoList.OrderBy(i => i.StartDate);
