.cs代码

  //IP查询省市

 

protected void BindIP(string strIP)         {            IpAddressSearchWebServiceSoap IpSearch = new IpAddressSearchWebServiceSoapClient("IpAddressSearchWebServiceSoap");             string[] infos = IpSearch.getCountryCityByIp(strIP);             char[] strcity = { ' ' };             string[] str = infos[1].ToString().Split(strcity);             //infos[1] 显示的是全部             Response.Write("IP是："+infos[0]+"  IP所在城市是："+str[0]);        }         protected void btnIP_Click(object sender, EventArgs e)         {             string strip = txtIP.Text;             BindIP(strip);         } html代码aspx  
       
     

第二种方法：

1.添加引用：

2.protected void Page_Load(object sender, EventArgs e)

        {

            IPServer.PAddressSoapClient paddres = new IPServer.PAddressSoapClient("IPAddressSoap");

            string st = paddres.GetIPCountry("117.89.57.254");

         }
