Try LINQ to go through the elements of the array and sort each one ..
int[][] ex_arr = new int[][] { new int[] { 32, 22, 0 }, new int[] { 33, 4, 12 }, new int[] { 9, 0, 0 } };
var qry = from x in ex_arr
select Sort(x);
int[][] sorted= qry.ToArray<int[]>();
add this function for sorting an array ... there might be a built in function for this ...
int[] Sort(int[] arr)
{
Array.Sort(arr);
return arr;
}
hope this helps
