Multidimensional Arraylist

[AccordingToDale]

Is it possible to create a multi-dimensional arraylist (not an array)?

I would imagine so. just add an array list to an array list.

I'm doing something like that now. Placing my values into a structure and sticking that in the arraylist.

But I thought maybe there was a cleaner way.

ps. Are all programmers anal?

if the values are a set group, then you could use a datatable to store them.

there's a thot. one tends to get stuck in rut when headlong into some process.

try the scientific aproach and try making a class and then a collectionclass (stronglytyped) and then a collectionclass of that collectionclass I think it would be a easier to understand.

If you want to use a multidimensional arraylist to store values of coordinates for example, you can convert the coordinates to absolute values and use an arraylist still. For example, (4,5) would translate to 5 * TotalNumberOfColumns + 4

If the total number of columns is 6, this would result in 34.

This way every coordinate is unique, assuming you use (0,0) for the upperleft corner. Translating it back into coordinates:

x = AbsoluteValue Mod TotalNumberOfColumns (34 mod 6 = 4)
y = Int(AbsoluteValue / TotalNumberOfColumns) (the integer part of (34 / 6 = 5.666666666) is 5)

I hope that may be useful.
