you cannot convert this string into two dimensional array. Try to put your question clearly here.

What is the issue your are facing?

I have a two dimensional array in java script like

var exArray = [[2, 3], [3, 4], [5, 6]];
These array values are stored in a hidden variable using json object.
document.getElementById("hdnArray").value = JSON.stringify(exArray);

In Code side, the hidden variable value as "[[2, 3], [3, 4], [5, 6]]".

Now I want to convert these hidden variable value into two dimensional array with out using spliting operation.

Hi dear ,
use this

C#

var sb = new StringBuilder();
sb.Append("1,1,2,2,0,0,a,b,c,d,1,1,2,2,0,1,e,f,g,h,1,1,2,2,0,1,x,y,x,z");
const int k = 3;
var items = sb.ToString().Split(',');
var len = items.Length;
var columns = ((len - 1) / k) + 1; //or (len/k) if (len%k==0)
string[,] result = new string[columns, k];
int c = -1;
int r = -1;
for (int i = 0; i < len; i++)
{
  string item = items[i];
  c = (c + 1) % columns;
  if (c == 0)
  {
    r++;
  }
  result[c, r] = item;
}
