C#获取本机IP搜集整理7种方法

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 }  

②使用IPHostEntry获取本机局域网地址

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 "WHITE-SPACE: pre">  IPHostEntry localhost = Dns.GetHostEntry(hostname); 6 IPAddress localaddr = localhost.AddressList[0]; 7 return localaddr.ToString(); 8 }  

③获取本机网络ip地址

方法时通过向网站向一些提供IP查询的网站发送webrequest，然后分析返回的数据流

 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.ip.cn/getip.php?action=getip&ip_url=&from=web 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  
				

					
					

						当前 IP：0.0.0.0 来自：XX省XX市 电信
					

					

						GeoIP: Beijing, China
					

				
15  解析这段就行 16 */ 

④//由于用到了ManagementClass、ManagementObjectCollection；必须添加引用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调用一个网站提供的Web服务来查询IP网址： http://www.webxml.com.cn/zh_cn/web_services.aspx服务： http://webservice.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx 弄了好半天，但是没学会怎样调用Web Service，按照搜到的页面做也不行，遂先放弃吧.....毕竟还未接触到WebService，改天把WebService搞定再来一定就容易了（留待以后完善吧）

⑥通过获取CMD里ipconfig命令的结果来得到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); 34 }
