Hi guys,

I would like to know how to store a SQL result into an 2d array.

The SQL result is a 13 x 25 table. Because i wish to do calcuations with each element in this result table, i would like each element to be a variable (hence a 2d a array seemed like the best solution).

Im just not sure how to write the SQL query result into a 2D Array.

Please help.

Use Jagged Array[^] to store and then do calculations as you wish.

Sample:

C#

int[][] sqlResult = new int[13][];
for (int x = 0; x < 12; x++)
{
   sqlResult[x] = new int[25];
}

If you return the result into a DataTable, it is already in a 2D array: Row downward, each having Cells across.

Ok,so how do I reference each element in the datatable for use in the rest of the code? is it the same as an array i.e Arrayname[i,j] ?

object o = myDataTable.Rows[rowNumber][colNumber];
