限制IP添加页CS代码

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HTMLControls;

public partial class admin_ip : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

Server.Execute("chklog.ASPx");

}

protected void Button1_Click(object sender, EventArgs e)

{

iplxb.Items.Add(iptb.Text);

odb.insert("insert into ip (ip) values ('" + iptb.Text + "')");

}

protected void LinkButton1_Click(object sender, EventArgs e)

{

for (int i = 0; i < iplxb.Items.Count; i++)

{

if (iplxb.Items[i].Selected)

{

odb.insert("delete from ip where ip='"+iplxb.SelectedItem.Text+"'");

iplxb.Items.Remove(iplxb.SelectedItem.Text);

}

}

}

}

被需要限制IP的页面调用页的代码

protected void Page_Load(object sender, EventArgs e)

{

string ip = Request.UserHostAddress.ToString();

if (Convert.ToInt32(odb.scr("select count(*) from [ip] where ip='" + ip + "'")) > 0)

Response.Write("对不起，您的IP被限制访问，请咨询管理员");

}

}
