.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
 
 <asp:TextBox ID="txtIP" runat="server"></asp:TextBox>
  <asp:Button ID="btnIP" runat="server" Text="IP查询城市" onclick="btnIP_Click" />

第二种方法：

1.添加引用：http://www.wjg121.cn/service/ipaddress.asmx

2.protected void Page_Load(object sender, EventArgs e)
        {
            IPServer.PAddressSoapClient paddres = new IPServer.PAddressSoapClient("IPAddressSoap");
            string st = paddres.GetIPCountry("117.89.57.254");
         }
