我正在创建一个 IP 跟踪器，它将连接到网络并从文本框中输入值 (IP) 并将接收结果。这是代码。

 using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    using System.Xml;

    namespace geoIP
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }

            private void button1_Click(object sender, EventArgs e)
            {
                iptrace();
            }

             public static string iptrace()
            {
                XmlDocument xmldoc = new XmlDocument();
                XmlNodeList xmlnode;
                int i;

                xmldoc.Load("http://freegeoip.net/xml/" + textBox1.Text);
                xmlnode = xmldoc.GetElementsByTagName("response");
                for (i = 0; i < xmlnode.Count; i++)
                {
                    xmlnode[i].ChildNodes.Item(0).InnerText.Trim();
                    label1.Text = "Ip Address: " + xmlnode[i].ChildNodes.Item(0).InnerText.Trim();
                    label2.Text = "Country Code: " + xmlnode[i].ChildNodes.Item(1).InnerText.Trim();
                    label3.Text = "Country Name: " + xmlnode[i].ChildNodes.Item(2).InnerText.Trim();
                    label4.Text = "Region Code: " + xmlnode[i].ChildNodes.Item(3).InnerText.Trim();
                    label5.Text = "Region Name: " + xmlnode[i].ChildNodes.Item(4).InnerText.Trim();
                    label6.Text = "City: " + xmlnode[i].ChildNodes.Item(5).InnerText.Trim();
                    label7.Text = "Zip Code: " + xmlnode[i].ChildNodes.Item(6).InnerText.Trim();
                    label8.Text = "Latitude: " + xmlnode[i].ChildNodes.Item(7).InnerText.Trim();
                    label9.Text = "Longitude: " + xmlnode[i].ChildNodes.Item(8).InnerText.Trim();
                    label10.Text = "Metro Code: " + xmlnode[i].ChildNodes.Item(9).InnerText.Trim();
                }

            }
