Pretty easy:

 public void PrintSql_Array()
    {
        int[] numbers = new int[4];
        string[] names = new string[4];
        string[] secondNames = new string[4];
        int[] ages = new int[4];

        int cont = 0;

        string cs = @"Server=ADMIN\SQLEXPRESS; Database=dbYourBase; User id=sa; password=youpass";
        using (SqlConnection con = new SqlConnection(cs))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.Connection = con;
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "SELECT * FROM tbl_Datos";
                con.Open();

                SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);

                foreach (DataRow row in dt.Rows)
                {
                    numbers[cont] = row.Field(0);
                    names[cont] = row.Field(1);
                    secondNames[cont] = row.Field(2);
                    ages[cont] = row.Field(3);

                    cont++;
                }

                for (int i = 0; i < numbers.Length; i++)
                {
                    Console.WriteLine("{0} | {1} {2} {3}", numbers[i], names[i], secondNames[i], ages[i]);
                }

                con.Close();
            }
        }
    }
