C#取得本機IP蒐集整理7種方法的範例程式碼分享
①
1 private void GetIP()
2 {
3 string hostName = Dns.GetHostName();//本机名
4 //System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，我运行时且只返回了一个IPv4的地址
5 System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6
6 foreach (IPAddress ip in addressList)
7 {
8 listBox1.Items.Add(ip.ToString());
9 }
10 }1 static string GetLocalIp()
2 {
3 string hostname = Dns.GetHostName();//得到本机名
4 //IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址
5 <SPAN style="WHITE-SPACE: pre"> </SPAN> IPHostEntry localhost = Dns.GetHostEntry(hostname);
6 IPAddress localaddr = localhost.AddressList[0];
7 return localaddr.ToString();
8 }方法時透過向網站向一些提供IP查詢的網站傳送webrequest，然後分析傳回的資料流
1 string strUrl = "提供IP查询的网站的链接";
2 Uri uri = new Uri(strUrl);
3 WebRequest webreq = WebRequest.Create(uri);
4 Stream s = webreq .GetResponse().GetResponseStream();
5 StreamReader sr = new StreamReader(s, Encoding.Default);
6 string all = sr.ReadToEnd();
7 int i = all.IndexOf("[") + 1;
8 //分析字符串得到IP 9 return ip;
10 /* 11 我用的是http://www.php.cn/
12 (这种链接很容易找的，百度“IP”得到一些网站，分析一下网站的链接就能得到)
13 返回的数据是：
14 <p class="well"><p>当前 IP：<code>0.0.0.0</code> 来自：XX省XX市 电信</p><p>GeoIP: Beijing, China</p></p>
15 解析这段就行
16 */ 1 private void GetIP2()
2 {
3 string stringMAC = "";
4 string stringIP = "";
5 ManagementClass managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration");
6 ManagementObjectCollection managementObjectCollection = managementClass.GetInstances();
7 foreach(ManagementObject managementObject in managementObjectCollection)
8 {
9 if ((bool)managementObject["IPEnabled"] == true)
10 {
11 stringMAC += managementObject["MACAddress"].ToString();
12 string[] IPAddresses = (string[])managementObject["IPAddress"];
13 if (IPAddresses.Length > 0)
14 {
15 stringIP = IPAddresses[0];
16 }
17 }
18 }
19 txtMAC.Text = stringMAC.ToString();
20 txtIP.Text = stringIP.ToString();
21 }⑤調用一個網站提供的Web服務來查詢IP網址
弄了好半天，但是沒學會怎樣調用Web Service，按照搜到的頁面做也不行，遂先放棄吧.....畢竟還未接觸到WebService，改天把WebService搞定再來一定就容易了（留待以後完善吧）
⑥透過取得CMD裡ipconfig指令的結果來得到IP
1 private void GetIP6()
2 {
3 Process cmd = new Process();
4 cmd.StartInfo.FileName = "ipconfig.exe";//设置程序名 5 cmd.StartInfo.Arguments = "/all"; //参数
6 //重定向标准输出 7 cmd.StartInfo.RedirectStandardOutput = true;
8 cmd.StartInfo.RedirectStandardInput = true;
9 cmd.StartInfo.UseShellExecute = false;
10 cmd.StartInfo.CreateNoWindow = true;//不显示窗口（控制台程序是黑屏）
11 //cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;//暂时不明白什么意思 12 /* 13 收集一下 有备无患
14 关于:ProcessWindowStyle.Hidden隐藏后如何再显示？
15 hwndWin32Host = Win32Native.FindWindow(null, win32Exinfo.windowsName);
16 Win32Native.ShowWindow(hwndWin32Host, 1); //先FindWindow找到窗口后再ShowWindow
17 */ 18 cmd.Start();
19 string info = cmd.StandardOutput.ReadToEnd();
20 cmd.WaitForExit();
21 cmd.Close();
22 textBox1.AppendText(info);
23 }
#⑦NetworkInformation
1 private void GetIP5()
2 {
3 //需要的命名空间
4 //using System.Net.NetworkInformation;
5 //using System.Net.Sockets; 6 string str = "";
7 NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
8 int i = 0;
9 foreach (NetworkInterface adapter in adapters)
10 {
11 12 IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
13 UnicastIPAddressInformationCollection allAddress =
14 adapterProperties.UnicastAddresses;
15 if (allAddress.Count > 0)
16 {
17 str += "interface " + i + "description:\n\t " + adapter.Description + "\n ";
18 i++;
19 foreach (UnicastIPAddressInformation addr in allAddress)
20 {
21 if (addr.Address.AddressFamily == AddressFamily.InterNetworkV6)
22 {
23 ipListComb.Items.Add(addr.Address);
24 }
25 if (addr.Address.AddressFamily == AddressFamily.InterNetwork)
26 {
27 comboBox1.Items.Add(addr.Address);
28 }
29 30 }
31 }
32 }
33 MessageBox.Show(str);
