C#擷取本機IP搜集整理7種方法的範例程式碼分享

①

 1 private void GetIP()   2 {   3     string hostName = Dns.GetHostName();//本機名    4     //System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//會警告GetHostByName()已到期，我運行時且只返回了一個IPv4的地址     5     System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//會返回所有地址，包括IPv4和IPv6     6     foreach (IPAddress ip in addressList)   7     {   8         listBox1.Items.Add(ip.ToString());   9     }  10 }

②使用IPHostEntry擷取本機區域網路地址

1         static string GetLocalIp()  2         {  3             string hostname = Dns.GetHostName();//得到本機名   4             //IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已到期，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         }

③擷取本機網路ip地址

方法時通過向網站向一些提供IP查詢的網站發送webrequest，然後分析返回的資料流

 1        string strUrl = "提供IP查詢的網站的連結";   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        //分析字串得到IP    9        return ip;  10        /* 11         我用的是http://www.php.cn/    12         (這種連結很容易找的，百度“IP”得到一些網站，分析一下網站的連結就能得到) 13         返回的資料是：  14         <p class="well"><p>當前 IP：<code>0.0.0.0</code>&nbsp;來自：XX省XX市 電信</p><p>GeoIP: Beijing, China</p></p>  15         解析這段就行  16       */

④//由於用到了ManagementClass、ManagementObjectCollection；必須添加引用System.Management.dll及using System.Management;

 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通過擷取CMD裡ipconfig命令的結果來得到IP

 1    private void GetIP6()   2    {   3        Process cmd = new Process();   4        cmd.StartInfo.FileName = "ipconfig.exe";//設定程式名    5        cmd.StartInfo.Arguments = "/all";  //參數    6 //重新導向標準輸出    7        cmd.StartInfo.RedirectStandardOutput = true;   8        cmd.StartInfo.RedirectStandardInput = true;   9        cmd.StartInfo.UseShellExecute = false;  10        cmd.StartInfo.CreateNoWindow = true;//不顯示視窗（控制台程式是黑屏）   11 //cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;//暫時不明白什麼意思   12        /* 13 收集一下 有備無患 14        關於:ProcessWindowStyle.Hidden隱藏後如何再顯示？ 15        hwndWin32Host = Win32Native.FindWindow(null, win32Exinfo.windowsName); 16        Win32Native.ShowWindow(hwndWin32Host, 1);     //先FindWindow找到視窗後再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     //需要的命名空間    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);  34        }
