I need to implement a for loop to generate an image animation. As shown in the attached imagehttp://i.stack.imgur.com/VCjKW.jpg[^] , if a user selects hbox=6 and vbox=4, an a 2-d array of 24 items will be created. Now we need to access these elements as follows:

1st iteration: [1][1]
2nd iteration: [2][1], [1][2]
3rd: [3][1],[2][2],[1][3]
4th: [4][1],[3][2],[2][3],[1][4]
5th: [4][2],[3][3],[2][4],[1][5]
and so on until the last iteration is [4][6]

So please provide me a for loop implementation to access the elements in such fashion.

This is not a good question. You need to explain what you try to achieve clearly. Please understand that example is not a formulation of a problem.

i just satisfy upto 4th iterations of your exmaple. The code is

C#

int hbox = 6;
int vbox = 4;
for (int r = 1; r <= hbox; r++)
{
   int x = 0;
   for (int c = 1; c <= vbox; c++)
   {
      string val = arr[r - x, c];
      x++;
      list.Add(val);
      if (r == c)
          break;
   }
}

But if 5th iteration i do not clear the varying part. There i saw row no is still same for iteration 4 and iteration 5. This requirement is little confused me. let me know the code will help you or not.
