C#获取本机IP搜集整理7种方法的示例代码分享
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.gxlsystem.com/ 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调用一个网站提供的Web服务来查询IP网址
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 }
