How to store 2D string array in a session?

Question

I have this 2D string array which is retrieving data from a database. Problem is, when i click a button, the array gets empty due to reload. I need to store it in a session or with any other way you guys suggest.

 //Declaration in the class 
 string[,] randomizedOptionalTable;



//In the function of retrieving the database
randomizedOptionalTable = new string[qIDSize, 4];
//Database retrieving code.
Session["keyRandomizedOptionalTable"] = randomizedOptionalTable;

I think what I'm storing in the Session is just the base address of the array.

I want the entire data to be stored in the Session. It would really help me if you guys have a solution for this or any different idea to store a string table with different way.

Check the sample, working for me...

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        ToSession();
        FromSession();
    }
}
private void ToSession() 
{ 
    string[,] strTo2D = { {"A"}, {"B"} };
    Session["str2DArray"] = strTo2D; 
}
private void FromSession() 
{
    string[,] strFrom2D = (string[,])Session["str2DArray"];
    Response.Write(strFrom2D[0, 0].ToString()); 
}
