推荐答案

请找到下面的代码块。

Please find the code block below.

<asp:Button Text="Click Me" ID="btn" runat="server" OnClick="btn_Click" />
            <asp:Panel ID="Panel1" runat="server">
            <asp:CheckBox Text="1" runat="server" ID="chk1" />
            <asp:CheckBox Text="2" runat="server" ID="chk2" />
            <asp:CheckBox Text="3" runat="server" ID="chk3" />
            <asp:CheckBox Text="4" runat="server" ID="chk4" />
            <asp:CheckBox Text="5" runat="server" ID="chk5" />
            <asp:CheckBox Text="6" runat="server" ID="chk6" />
            <asp:CheckBox Text="7" runat="server" ID="chk7" />
            <asp:CheckBox Text="8" runat="server" ID="chk8" />
            <asp:CheckBox Text="9" runat="server" ID="chk9" />
            <asp:CheckBox Text="10" runat="server" ID="chk10" />
            </asp:Panel>
            <asp:Label Text="" ID="lbl" runat="server" />

以下是代码背后的代码

Below is the code behind

protected void btn_Click(object sender, EventArgs e)
        {
            List<int> values = new List<int>();
            foreach (Control item in Panel1.Controls)
            {
                if (item.GetType().ToString().Equals("System.Web.UI.WebControls.CheckBox"))
                {
                    CheckBox c = (CheckBox)item;
                    if (c.Checked)
                        values.Add(Convert.ToInt16(c.Text));
                }
            }

            if (values.Count > 0)
            {
                values.Sort();
                lbl.Text = values[0] + " - " + values[values.Count - 1];
            }
        }
