資料繫結技巧：Hashtable 繫結至 RadioButtonList

void Page_Load(object sender, System.EventArgs e)
{
    if(!IsPostBack)
    {
        Hashtable hash = new Hashtable();
        hash.Add("北京", "010"); hash.Add("廣州", "020"); hash.Add("上海", "021");
        hash.Add("天津", "022"); hash.Add("成都", "028"); hash.Add("濟南", "0531");
        RadioButtonList1.DataSource = hash;
        RadioButtonList1.DataTextField = "Key";
        RadioButtonList1.DataValueField = "Value";
        RadioButtonList1.DataBind();
    }
}
