Get ASP.Net DropDownList selected Text using C#

I am getting here selected value as 18(id of the country) and i am checking it for if condition.

private void loadinvoicedetails()
{
     lstCountryy.SelectedValue = dtInquiry.Rows[0]["country"].ToString();
}

            if (lstCountryy.SelectedValue == "U.A.E" || lstCountryy.SelectedValue == "BAHRAIN" || lstCountryy.SelectedValue == "SAUDI ARABIA")
            {
                txtvat.Text = "";
                txtvatt.Text = "";
                txtBankCharge.Text = "";
                txtDiscount.Text = "";
                txtDiscountText.Text = "";
                txtTotal.Text = "";
                vattr.Style.Add("display", "float");
                trdeclaration.Visible = false;

                //txtvat.Enabled = true;
            }
            else
            {
                txtvat.Text = "";
                txtvatt.Text = "";
                txtBankCharge.Text = "";
                txtDiscount.Text = "";
                txtDiscountText.Text = "";
                txtTotal.Text = "";

                vattr.Style.Add("display", "none");

                trdeclaration.Visible = true;
            }

so it is checking for 18==UAE.

How to get the name instead of id?
