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> 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); } 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？
