How to access the position of radiobuttonlist items in asp?

Question

I am developing a radiobutton list in asp. I need to access the items of radiobutton list one

 while (reader.Read())
            {
                RadioButtonList1.Items.Add(reader["options"].ToString());


            }

what I need to do is check the first item in the list. I am very beginner in ASP. Just started couple of day back.

要检查第一项，只需使用：

RadioButtonList1.Items[0].Selected = true;
