This isn't what you asked for but maybe a list of 2-tuples might be useful:

if you know the dimensions bevor you do it by this (somehow weird) syntax:

int [, ] array2d = new int [4, 2];

Open in new window


if not you may use a List

List< List<Node> > array2d = new List< List<Node> > ;
array2d.Add(new List<Node>);

array2d[0].Add(new Node(7, 53));

Open in new window


(i hope the syntax is correct).

I don't think you'll want sarabande's array syntax. That defines a square array, which means both dimensions are fixed to what you declare them as. You probably want an array of arrays. It's somewhat related to a square array, but the only the first dimension is fixed--the 2nd dimension is dynamic:

int[][] array2d = new int[5][];

It's similar, in effect, to the list of lists that sarabande purposes.
