2-dimensional ArrayList

[Iwanow]

Hello!

Is it possible to use ArrayList as a 2-dimensional list? I want to keep
a bitmap in it, and I would like to access its elements by providing
two parameters (row and column) rather than calculating offset from the
begin. Thanks in advance for any hints.

AFAIK, no. Feel free to research here:

Call me an idiot but what's wrong with a wrapper that
simply combines to indices into one (assuming the
OP really wants a 2-dimensional array - I'm not sure
what a 2-dimensional list would be)?

I.e. x[a,b] =y[a+b*dim(0)]

There are several ways to allocate the backing
store for the memory. Depending on the
requirements (specifically do the dimensions
change frequently?) you could also use a
CLR array which can have more than one
dimension, but has constant size for its
lifetime.

Oc, it might be useful to use a packed representation
if the logical element value range doesn't require all
bits of its physical backing store.

It really sounds like the OP wants either a CLR array
( array<X,N>^ where N>1) or a wrapper around a CLR vector
(array<X>^) with a custom indexer.
