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？
