2D Arrays

When you say add, do you mean you want to add arithmetically as in 2 + 2 or do you mean put values into the array?

I think that an array with "name" and "age" is not a 2D array; I think it is a 1D array of objects with members "name" and "age".

A DataTable stores the data as a collection, and a collection is like an array. An array is a type of collection. So a DataTable is very efficient for most things. Your time is valuable; the computer is cheap compared to your time and the time of other programmers. You should use resources that make your time efficient. For most applications, a DataTable is a very productive solution. If you know how to use a DataTable to do what you need to do, then use a DataTable.
