        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
 后台：
  protected void Button1_Click(object sender, EventArgs e)
        {
            if (CheckBox1.Checked == true)
            {
                Response.Write("1");
            }
            if (CheckBox2.Checked == true)
            {
                Response.Write("2");
            }
            if (CheckBox3.Checked == true)
            {
                Response.Write("3");
            }
        }
