asp.net 使用radiobuttonlist的困惑 (使用关键词New创建实例)解决思路

asp.net 使用radiobuttonlist的困惑 (使用关键词New创建实例)
折腾了一天了，精疲力尽了已经。贴到这里求救，救命啊！
页面部分：
<body>
<form id= "form1 " runat= "server ">
<div>
<asp:RadioButtonList ID= "RadioButtonList1 " runat= "server ">
</asp:RadioButtonList> </div>
<asp:Button ID= "Button1 " runat= "server " OnClick= "Button1_Click " Text= "Button " />
</form>
</body>
</html> cs部分方案一：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.RadioButtonList1.Items.Add(new ListItem( "test1 ", "test1 "));
this.RadioButtonList1.Items.Add(new ListItem( "test2 ", "test2 "));
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(this.RadioButtonList1.SelectedItem.Value);
}cs部分方案二：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.RadioButtonList1.Items.Add(new ListItem( "test1 ", "test1 "));
this.RadioButtonList1.Items.Add(new ListItem( "test2 ", "test2 "));
}
}
protected void Button1_Click(object sender, EventArgs e)
{
RadioButtonList rbl = new RadioButtonList();
rbl = (RadioButtonList)Page.FindControl( "RadioButtonList1 ");
Response.Write(rbl.SelectedItem.Value);
}
尝试阿尝试，无尽的尝试，最终还是一个“请使用关键词New创建实例”，已经无语了，高手路过，请抽时间帮帮小弟，现在都共产主义社会了，总该有点共产主义精神吧？

把你的方案一改了一下
如下代码
ＣＳ代码
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.RadioButtonList1.Items.Add(new ListItem( "test1 ", "test1 "));
