遍历页面上所有的RadioButton与CheckBox出现一个奇怪的有关问题.请大家帮忙看一下

性别     <asp:RadioButton ID="r1_1" runat="server" GroupName="g1" Text="男" />    <asp:RadioButton ID="r1_2" runat="server" GroupName="g1" Text="女" />    <br />选择    <asp:CheckBox ID="c1_1" runat="server" Text="选择1" />    <br />    <asp:CheckBox ID="c1_2" runat="server" Text="选择2"/>    <br />

foreach (Control cl in this.form1.Controls)            {                if (cl is RadioButton)                {                    RadioButton tempR = ((RadioButton)cl);if (tempR.Checked)                    {//此处省略                    }                }                if (cl is CheckBox)                {                    CheckBox tempC = ((CheckBox)cl);if (tempC.Checked)                    {                        //此处省略                    }                }            }
