based on the example from c-sharpcorner.com. Modify the following line

SqlCommand cmd = new SqlCommand("select County,CountryId from Country", conn);
SqlDataReader dr = cmd.ExecuteReader();

SqlCommand cmd = new SqlCommand("GetCountry", conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
SqlDataReader dr = cmd.ExecuteReader();
