.net如何遍历checkbox?

<asp:CheckBox ID="CheckBox1" runat="server" name="Admin_Power" Text=" 投票1" />
<asp:CheckBox ID="CheckBox2" runat="server" name="Admin_Power" Text=" 投票2" />
<asp:CheckBox ID="CheckBox3" runat="server" name="Admin_Power" Text=" 投票3" />
<asp:CheckBox ID="CheckBox4" runat="server" name="Admin_Power" Text=" 投票4" />
<asp:CheckBox ID="CheckBox5" runat="server" name="Admin_Power" Text=" 投票5" />
<asp:CheckBox ID="CheckBox6" runat="server" name="Admin_Power" Text=" 投票6" />
页面里有N组这种CheckBox
请问在后台里如何遍历name为Admin_Power的CheckBox

楼上的大哥我有很多不明白的地方
FindBox在哪调用？如何调用？cc是什么？
完整的方法

      }      if (c is CheckBox)
      {
        CheckBox x = c as CheckBox;
        //判断名称
        if (x.Attributes["name"] != null && x.Attributes["name"].Equals("Admin_Power"))
        {
          Response.Write("<li>" + x.Attributes["name"]);

这个方法可不可以返回string类型的值啊？
知道出处了。哎，一次把需求说清楚多好。private string FindBox(ControlCollection cc)
        {

            string str = "";
            foreach (Control c in cc)
            {
                if (c is CheckBox)
                {
                    CheckBox x = c as CheckBox;
                    //判断名称
                    if (x.Attributes["name"] != null && x.Attributes["name"].Equals("Admin_Power") && x.Checked == true)
                    {
                        str += x.Text + ",";
                    }
                }                if (c.HasControls())
                {
                    str = FindBox(c.Controls);
                }
            }
            return str;
        }        protected void Button1_Click(object sender, EventArgs e)
        {
            string result = FindBox(Page.Controls);
            result = result.Substring(0, result.Length - 1);
        }
