.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");
}
