untested code:

--------------
string[,] marked = (string[,])Session["marked"];

if (marked == null)
{
// nothing yet in session, so create it
marked = new string[50][2];
Session["marked"] = marked;
}

// use it
marked[12, 1] = "test";
-------------

Note: as you have a *reference* to this array, there is really only one array
so a change to 'marked' will "also update" the array "stored in the Session"
(to phrase it loosely). No need to "put the changed array back in the Session".
