how to save all row of session data into database

hi

I have two page in first page when click button it will save data in session below is code:

 protected void Imgorder_Click(object sender, EventArgs e)
    {
        ImageButton ibtn = sender as ImageButton;
        int id = Convert.ToInt32(Request.QueryString["Id"].ToString());
        DataTable dtFiles = GetFilmInfo(id);
        string Name = dtFiles.Rows[0][1].ToString();
        string MKVE = dtFiles.Rows[0][37].ToString();
        string DVDE = dtFiles.Rows[0][38].ToString();
        string PostMkvPr = dtFiles.Rows[0][12].ToString();
        string PostDvdPr = dtFiles.Rows[0][13].ToString();
        string Code = dtFiles.Rows[0][4].ToString();
        string Type = dtFiles.Rows[0][36].ToString();
        string SectionName = dtFiles.Rows[0][3].ToString();
        DataTable dt = new DataTable();
        if (Session["Order"] != null)
        {
            dt = Session["Order"] as DataTable;
        }
        else
        {
            dt.Columns.AddRange(new DataColumn[] { new DataColumn("Id",typeof(int)),new DataColumn("Name",typeof(string)),new DataColumn("Quality",typeof(string)),
                                       new DataColumn("PriceT", typeof(decimal)),  new DataColumn("Price", typeof(decimal)), new DataColumn("Quanyity", typeof(int)),new DataColumn("code",typeof(string)),new DataColumn("Type",typeof(string))
                                       ,new DataColumn("SectionName",typeof(string)),
                                        new DataColumn("buy",typeof(string)),new DataColumn("show",typeof(string)),});

        }
        if (RBmkv.Checked || RBdvd.Checked)
        {

            if (RBmkv.Checked)
            {
                DataRow duplicate = (from d in dt.AsEnumerable()
                                     where d.Field<string>("Quality") == "MKV"
                                     && d.Field<string>("Name") == Name
                                     select d).FirstOrDefault();
                if (duplicate != null)
                {
                    int qty = Convert.ToInt32(duplicate.ItemArray[5]);
                    duplicate["Quanyity"] = (qty + 1);
                    duplicate["PriceT"] = (int.Parse(PostMkvPr) * (qty + 1));
                    dt.AcceptChanges();
                }
                else
                {
                    dt.Rows.Add(dt.Rows.Count + 1, Name, "MKV", PostMkvPr, PostMkvPr, MKVE, Code, Type, SectionName, "خرید پستی", "Buy");
                }
            }
            if (RBdvd.Checked)
            {
                DataRow duplicate = (from d in dt.AsEnumerable()
                                     where d.Field<string>("Quality") == "DVD" && d.Field<string>("Name") == Name
                                     select d).FirstOrDefault();
                if (duplicate != null)
                {
                    int qty = Convert.ToInt32(duplicate.ItemArray[5]);
                    duplicate["Quanyity"] = (qty + 1);
                    duplicate["PriceT"] = (int.Parse(PostDvdPr) * (qty + 1));
                    dt.AcceptChanges();
                }
                else
                {
                    dt.Rows.Add(dt.Rows.Count + 1, Name, "DVD", PostDvdPr, PostDvdPr, DVDE, Code, Type, SectionName, "خرید پستی", "Buy");
                }
                int totalOrder = dt.AsEnumerable().Sum(row => row.Field<int>("Quanyity"));
                Lblorder.Text = totalOrder.ToString();
                Response.Cookies["UserName"].Value = Lblorder.Text.Trim();
            }
        }
    }

it will save data in session in some rows like below:

now in other page I wrote some code that I want it will save session valuse in database:

protected void LBsabt_Click(object sender, EventArgs e)
{
    using (SqlConnection conn = General.GetConnection())
    {
        using (SqlCommand _cmd = General.GetCommand("Oreder_Insert", conn))
        {
            DataTable dtOrder = Session["Order"] as DataTable;
            conn.Open();
            _cmd.Parameters.AddWithValue("@UserName", LblName.Text);
            _cmd.Parameters.AddWithValue("@Mobile", LblMob.Text);
            _cmd.Parameters.AddWithValue("@Tell", LblTell.Text);
            _cmd.Parameters.AddWithValue("@code", dtOrder.Rows[0]["Code"]);
            _cmd.Parameters.AddWithValue("@type", dtOrder.Rows[0]["Type"]);
            _cmd.Parameters.AddWithValue("@SectionName", dtOrder.Rows[0]["SectionName"]);
            _cmd.Parameters.AddWithValue("@Name", dtOrder.Rows[0]["Name"]);
            _cmd.ExecuteNonQuery();
        }
    }
}

now here it will save session["oreder"] values in database but one row of it I mean it just save below info from above table(just one row of data):

but I want it will save all data from session:

Like below:
