偶做留言本的时候想起做这么个,具体思路也许不好,做出来只是抛砖引玉,希望有更好的方法!
IP添加页是用了一个ListBox, TextBox,两个Button
而在其他的页上则直接用当前IP对比数据库中的IP,代码如下!
限制IP添加页HTML代码
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ip.aspx.cs" Inherits="admin_ip" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">
<div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:book %>"

<asp:ListBox ID="iplxb" runat="server" DataSourceID="SqlDataSource1" DataTextField="ip"
DataValueField="ip" Height="194px" Width="153px"></asp:ListBox></td>

填写标准的ＩＰ地址到左下文本框里面，然后点击按纽添加！<br />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="iptb"
Display="Dynamic" ErrorMessage="ＩＰ地址格式不正确" ValidationExpression="([0-9]{2,3})([.])([0-9]{1,3})([.])([0-9]{1,3})([.])([0-9]{1,3})"></asp:RegularExpressionValidator></td>
