ASP.NET:正在反序列化服务器端对象

你一定要这样做吗?为什么不使用 RadioButtonList ?

<form id="form1" runat="server">
    <div>
        <asp:RadioButtonList ID="RadioButtonList1" runat="server" DataSourceID="SqlDataSource1"
            DataTextField="year" DataValueField="year">
        </asp:RadioButtonList><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:tempdbConnectionString %>"
            SelectCommand="Select 2009 as year&#13;&#10;union all&#13;&#10;select 2008 as year&#13;&#10;union all&#13;&#10;select 2007 as year&#13;&#10;union all&#13;&#10;select 2006 as year&#13;&#10;union all&#13;&#10;select 2005 as year">
        </asp:SqlDataSource>
    </div>
</form>
