c# - n-dimensional Array -

i want create n-dimensional array of doubles. @ compile-time, number of dimensions n not known.

i ended defining array dictionary, key being array of ints corresponding different axes (so in 3-dimensional array, i'd supply [5, 2, 3] double @ (5, 2, 3) in array.

however, need populate dictionary doubles (0, 0, ... 0) (m1, m2, ... mn), m1 mn length of each axis.

my initial idea create nested for-loops, still don't know how many i'd need (1 each dimension), can't @ compile-time.

i hope i've formulated question in understandable manner, feel free ask me elaborate parts.

to create n-dimensional array, can use array.createinstance method:

array array = array.createinstance(typeof(double), 5, 3, 2, 8, 7, 32));  array.setvalue(0.5d, 0, 0, 0, 0, 0, 0); double val1 = (double)array.getvalue(0, 0, 0, 0, 0, 0);  array.setvalue(1.5d, 1, 2, 1, 6, 0, 30); double val2 = (double)array.getvalue(1, 2, 1, 6, 0, 30); 

to populate arrays, can use rank property , getlength method return length of current dimension, using couple of nested loops o(n^m) algo (warning - untested):

private bool increment(array array, int[] idxs, int dim) {     if (dim >= array.rank) return false;      if (++idxs[idxs.length-dim-1] == array.getlength(dim)) {         idxs[idxs.length-dim-1] = 0;         return increment(array, idxs, dim+1);     }     return true; }  array array = array.createinstance(typeof(double), ...); int[] idxs = new int[array.rank]; while (increment(array, idxs, 0)) {     array.setvalue(1d, idxs); }
