C#获取本机IP搜集整理几种方法 .net

1、//GetHostName private void GetIP() { string hostName = Dns.GetHostName(); //本机名 //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 System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName); //会返回所有地址，包括IPv4和IPv6 foreach (IPAddress ip in addressList) { listBox1.Items.Add(ip.ToString()); } }

2、使用IPHostEntry获取本机局域网地址

static string GetLocalIp() { string hostname = Dns.GetHostName(); //得到本机名 //IPHostEntry localhost = Dns.GetHostByName(hostname); //方法已过期，只得到IPv4的地址 IPHostEntry localhost = Dns.GetHostEntry(hostname); IPAddress localaddr = localhost.AddressList[0]; return localaddr.ToString(); }

3、获取本机网络ip地址

string strUrl = "提供IP查询的网站的链接"; Uri uri = new Uri(strUrl); WebRequest webreq = WebRequest.Create(uri); Stream s = webreq .GetResponse().GetResponseStream(); StreamReader sr = new StreamReader(s, Encoding.Default); string all = sr.ReadToEnd(); int i = all.IndexOf("[") + 1; //分析字符串得到IP return ip; /* 我用的是http://www.ip.cn/getip.php?action=getip&ip_url=&from=web (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) 返回的数据是：当前 IP：0.0.0.0 来自：XX省XX市电信【C#获取本机IP搜集整理几种方法】GeoIP: Beijing, China 解析这段就行 */

4、//由于用到了ManagementClass、ManagementObjectCollection；必须添加引用System.Management.dll及using System.Management;

private void GetIP2() { string stringMAC = ""; string stringIP = ""; ManagementClass managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection managementObjectCollection = managementClass.GetInstances(); foreach(ManagementObject managementObject in managementObjectCollection) { if ((bool)managementObject["IPEnabled"] == true) { stringMAC += managementObject["MACAddress"].ToString(); string[] IPAddresses = (string[])managementObject["IPAddress"]; if (IPAddresses.Length > 0) { stringIP = IPAddresses[0]; } } } txtMAC.Text = stringMAC.ToString(); txtIP.Text = stringIP.ToString(); }

5、通过获取CMD里ipconfig命令的结果来得到IP

private void GetIP6() { Process cmd = new Process(); cmd.StartInfo.FileName = "ipconfig.exe"; //设置程序名 cmd.StartInfo.Arguments = "/all"; //参数 //重定向标准输出 cmd.StartInfo.RedirectStandardOutput = true; cmd.StartInfo.RedirectStandardInput = true; cmd.StartInfo.UseShellExecute = false; cmd.StartInfo.CreateNoWindow = true; //不显示窗口（控制台程序是黑屏） //cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; //暂时不明白什么意思 /* 收集一下有备无患关于:ProcessWindowStyle.Hidden隐藏后如何再显示？ hwndWin32Host = Win32Native.FindWindow(null, win32Exinfo.windowsName); Win32Native.ShowWindow(hwndWin32Host, 1); //先FindWindow找到窗口后再ShowWindow */ cmd.Start(); string info = cmd.StandardOutput.ReadToEnd(); cmd.WaitForExit(); cmd.Close(); textBox1.AppendText(info); }

6、NetworkInformation

private void GetIP5() { //需要的命名空间 //using System.Net.NetworkInformation; //using System.Net.Sockets; string str = ""; NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces(); int i = 0; foreach (NetworkInterface adapter in adapters) {IPInterfaceProperties adapterProperties = adapter.GetIPProperties(); UnicastIPAddressInformationCollection allAddress = adapterProperties.UnicastAddresses; if (allAddress.Count > 0) { str += "interface" + i + "description:\n\t " + adapter.Description + "\n "; i++; foreach (UnicastIPAddressInformation addr in allAddress) { if (addr.Address.AddressFamily == AddressFamily.InterNetworkV6) { ipListComb.Items.Add(addr.Address); } if (addr.Address.AddressFamily == AddressFamily.InterNetwork) { comboBox1.Items.Add(addr.Address); }} } } MessageBox.Show(str); }
