C语言获取本机IP地址
C#获取本机IP地址（ipv4）
C#获取本机IP地址（ipv4）获取本机所有IP地址：这些地址是包含所有⽹卡（虚拟⽹卡）的ipv4和ipv6地址。
string name = Dns.GetHostName();IPAddress[] ipadrlist = Dns.GetHostAddresses(name);获取本机所有IPV4地址：string name = Dns.GetHostName();IPAddress[] ipadrlist = Dns.GetHostAddresses(name);foreach (IPAddress ipa in ipadrlist){if (ipa.AddressFamily == AddressFamily.InterNetwork)Console.Writeline(ipa.ToString());}若要单单获取ipv4地址，可以⽤IPAdress.AddressFamily 属性判断：对于 IPv4，返回 InterNetwork；对于 IPv6，返回InterNetworkV6。
然⽽如果本机可能有多个ipv4的地址，那如何获取访问默认⽹关时使⽤的⽹卡IP呢。
在CSDN论坛找到了⼤神的⽅法，⽤的是查询本机路由表。
获取本机正在使⽤的ipv4地址(访问互联⽹的IP)可别⼩看，还是有很多需要考虑的：1.⼀个电脑有多个⽹卡，有线的、⽆线的、还有vmare虚拟的两个⽹卡。
2.就算只有⼀个⽹卡，但是该⽹卡配置了N个IP地址.其中还包括ipv6地址。

C#获取本地IP的四种方式示例详解
C#获取本地IP的四种⽅式⽰例详解1.第⼀种⽅式采⽤.Dns的GetHostAddress的⽅式，具体请看代码：/// <summary>/// ⽹络不通畅可以获取/// 不过能获取到具体的IP/// </summary>/// <returns></returns>public static List<IPAddress> GetByGetHostAddresses(){try{IPAddress[] adds = Dns.GetHostAddresses(Dns.GetHostName());return adds == null || adds.Length == 0 ? new List<IPAddress>() : adds.ToList<IPAddress>();}catch (Exception){return new List<IPAddress>();}}这种⽅式受到⽹络的影响，如果没有连接到⽹络，本地配置的部分IP是获取不到的，我也遇到⼀种情况是，电脑环境正常，就是获取不到，原因⾄今还不知道；2.第⼆种⽅式采⽤System.Management.ManagementClass来获取，详细请看代码：/// <summary>/// 只有⽹络通畅才能获取/// </summary>/// <returns></returns>public static List<IPAddress> GetByManagementClass(){try{ManagementClass mClass = new System.Management.ManagementClass("Win32_NetworkAdapterConfiguration");ManagementObjectCollection managementObjectCollection = mClass.GetInstances();List<IPAddress> ls = new List<IPAddress>();foreach (var item in managementObjectCollection){if ((bool)item["IPEnabled"] == true){foreach (var ip in (string[])item["IPAddress"]){IPAddress ipout = null;IPAddress.TryParse(ip, out ipout);if (ipout != null){ls.Add(ipout);}}}}return ls;}catch (Exception){return new List<IPAddress>();}}同样的这种⽅式也受到⽹络的约束，没有联⽹的状态下不⼀定能够获取到IP；3.第三种⽅式我们平时在命令⾏中输⼊ipconfig命令同样也是能获取，在程序中启动Ipconfig应⽤程序，然后解析出来，也是可以获取得到IP,详细请看代码：public static List<IPAddress> GetByCMD(){try{Process cmd = new Process();cmd.StartInfo.FileName = "ipconfig.exe";cmd.StartInfo.Arguments = "/all";cmd.StartInfo.RedirectStandardOutput = true;cmd.StartInfo.RedirectStandardInput = true;eShellExecute = false;cmd.StartInfo.CreateNoWindow = true;cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;cmd.Start();string info = "";List<IPAddress> ls = new List<IPAddress>();// info = cmd.StandardOutput.ReadToEnd();Regex validipregex = new Regex(@"\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}");//new Regex(@"^(([1-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([1-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$");while ((info = cmd.StandardOutput.ReadLine()) != null){IPAddress ip = null;Console.WriteLine(info);info = validipregex.Match(info).Value;IPAddress.TryParse(info, out ip);if (ip != null){ls.Add(ip);}}cmd.WaitForExit();cmd.Close();return ls;}catch (Exception){return new List<IPAddress>();}}即便是通过这种⽅式来获取IP,如果在本机电脑没有联⽹的状态下，也是获取不到IP的，并且也不太建议使⽤这种⽅式；4.第四种⽅法采⽤NetworkInterface.GetAllNetworkInterfaces的⽅式是不受⽹络的影响的，联⽹或者不联⽹都能够获取到IP，详细请看代码：/// <summary>/// ⽆论⽹络通不通都能获取到Ip/// </summary>/// <returns></returns>public static List<IPAddress> GetByNetworkInterface(){try{NetworkInterface[] intf = NetworkInterface.GetAllNetworkInterfaces();List<IPAddress> ls = new List<IPAddress>();foreach (var item in intf){IPInterfaceProperties adapterPropertis = item.GetIPProperties();UnicastIPAddressInformationCollection coll = adapterPropertis.UnicastAddresses;foreach (var col in coll){ls.Add(col.Address);}}return ls;}catch (Exception){return new List<IPAddress>();}}以上所说的联⽹，包括连接在局域⽹中。
用MFC如何获取本地主机名和IP地址
1.在文件StdAfx.h文件里面加入#include <afxsock.h>
2.在MFC工程文件name+APP.cpp里面对socket初始化
for( i = 0; pHost!= NULL && pHost->h_addr_list[i]!= NULL; i++ )
{
char str[100];
char addr[20];
int j;
LPCSTR psz=inet_ntoa (*(struct in_addr *)pHost->h_addr_list[i]);
if (!AfxSocketInit())
{
return FALSE;
}
并且
在BOOL CDsfsdApp::InitInstance()文件里面重启socket服务器在return FALSE前加上
WSADATA wsaData;
WSAStartup(MAKEWORD(1,1),&wsaData);
再添加一个ExitInstance方法
如
int CDsfsdApp::ExitInstance()
{
WSACleanup();
return CWinApp::ExitInstance();
}
3.在窗体的单击事件下，写下面代码
void CDsfsdDlg::OnQuery()
{
char szHostName[128];

C语言获取IP和MAC码
首先看从C语音的几种方法比较起，看看如下，结果是获取IP和MAC码C#遍历局域网的几种方法及比较扫描局域网IP列表的几种方法很多软件都有获知局域网在线计算机IP的功能，但是在.net怎么实现呢，有好多方法，下面我给大家介绍几种，供大家参考。
1、微软社区上介绍了使用Active Directory 来遍历局域网利用DirectoryEntry组件来查看网络网址：/china/communITy/program/originalarticles/techdoc/DirectoryEntry.mspx private void EnumComputers(){using(DirectoryEntry root = new DirectoryEntry("WinNT:")){foreach(DirectoryEntry domain in root.Children){Console.WriteLine("Domain | WorkGroup: "+);foreach(DirectoryEntry computer in domain.Children){Console.WriteLine("Computer: "+);}}}}效果评价：速度慢，效率低，还有一个无效结果 Computer: Schema 使用的过程中注意虑掉。
2、利用Dns.GetHostByAddress和IPHostEntry遍历局域网private void EnumComputers(){for (int i = 1; i <= 255; i++){string scanIP = "192.168.0." + i.ToString();IPAddress myScanIP = IPAddress.Parse(scanIP);IPHostEntry myScanHost = null;trymyScanHost = Dns.GetHostByAddress(myScanIP);}catch{continue;}if (myScanHost != null){Console.WriteLine(scanIP+"|"+myScanHost.HostName);}}}效果评价：效率低，速度慢，不是一般的慢。
C#获取计算机名跟IP地址
bel1 = new bel ( ) ;
bel2 = new bel ( ) ;
//先继承一个Label 类
label1.Location = new System.Drawing.Point ( 24 , 16 ) ;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Fixed3D ;
// 设定窗体的边界类型
this.ForeColor = System.Drawing.SystemColors.Desktop ;
this.Font = new System.Drawing.Font ( "宋体" , 10 , System.Drawing.FontStyle.Bold ) ;
//先继承一个Label 类
label1.Location = new System.Drawing.Point ( 24 , 16 ) ;
label2.Location = new System.Drawing.Point ( 44 , 36 ) ;
//设定 Label的显示位置
label1.Text = "主机名称：" .Dns.GetHostName ( ) ;
this.Controls.Add ( bel1 ) ;
this.Controls.Add ( bel2 ) ;
}
private static string getIPAddress ( )
{
.IPAddress addr;
// 获得本机局域网IP地址
在前面已经说了，GetHostByName ( )方法的返回值时IPHostEntry 对象，此对象的属性 AddressList，是一个IPAddress类型的数组，包含了计算机此时的所有的IP地址信息。在ip01.cs中AddressList [0].Address是固定的IP地址，而对于上网动态分配的IP地址是.AddressList [1].Address。据此我们可以的得到读取拨号上网动态分配的IP地址的源程序：

C语言获取计算机的IP地址
C语言获取计算机的IP地址获取计算机的IP地址是计算机网络编程中的一个重要环节。
在C语言中，可以通过调用操作系统提供的网络相关的函数来获取IP地址。
下面将介绍在Windows和Linux操作系统上获取IP地址的方法。
一、Windows平台：Windows平台上获取IP地址可以使用Winsock库提供的函数。
下面是一个使用Winsock库获取IP地址的示例代码：```c#include <stdio.h>#include <winsock2.h>int maiWSADATA wsaData;int iResult;char hostname[256];struct hostent* host;char* ip;// 初始化Winsock库iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);if (iResult != 0)printf("WSAStartup failed: %d\n", iResult);return 1;}//获取本机主机名iResult = gethostname(hostname, sizeof(hostname));if (iResult != 0)printf("gethostname failed: %d\n", WSAGetLastError(); WSACleanup(;return 1;}//根据主机名获取主机信息host = gethostbyname(hostname);if (host == NULL)printf("gethostbyname failed: %d\n", WSAGetLastError(); WSACleanup(;return 1;}//获取IP地址字符串ip = inet_ntoa(*(struct in_addr*)host->h_addr_list[0]);printf("IP Address: %s\n", ip);// 释放Winsock库资源WSACleanup(;return 0;```该示例代码使用了Winsock库提供的函数`gethostname`和`gethostbyname`来获取本机主机名和主机信息，然后通过`inet_ntoa`函数将主机信息中的IP地址转换为字符串打印出来。
C语言获取Linux系统的IP地址和MAC地址
实际环境和特殊需求往往会将简单问题复杂化，比如计算机IP地址，对于一个连接中socket，可以直接获得本端和对端的IP、端口信息。
但在一些特殊场合我们可能需要更多的信息，比如系统中有几块网卡，他们的Mac地址是多少，每块网卡分配了几个IP（一个网卡对应多个IP）等等。
这些信息往往需要通过ifconfig指令来获得，对于程序员来说，在代码中调用外部的shell 指令可不是个最佳方案，因为没人能保障不同平台、不同版本的ifconfig指令输出的格式是一致的。
本篇文章中将介绍通过ioctl函数实现上述需求。
#includeint ioctl(int fd, int request, … );返回：成功返回0，失败返回-1ioctl函数的参数只有3个，但却是Unix中少有的几个“家族类”复杂函数，这里摘录一段《Unix网络编程》一书中对ioctl函数的描述：在传统上ioctl函数是用于那些普遍使用、但不适合归入其他类别的任何特殊的系统接口……网络程序（一般是服务器程序）中ioctl常用于在程序启动时获得主机上所有接口的信息：接口的地址、接口是否支持广播、是否支持多播，等等。
ioctl函数的第一个参数fd，可以表示一个打开的文件（文件句柄）或网络套接字，第二个和第三个参数体现了函数的家族特色，参数二request根据函数功能分类定义了多组宏，而参数三总是一个指针，指针的类型依赖于参数二request。
因为ioctl的种类实在太多，这里只列出和本文相关的几个参数定义：分类参数二（宏）参数三描述接口SIOCGIFCONF struct ifconf 获得所有接口列表SIOCGIFADDR struct ifreq 获得接口地址SIOCGIFFLAGS struct ifreq 获得接口标志SIOCGIFBRDADDR struct ifreq 获得广播地址SIOCGIFNETMASK struct ifreq 获得子网掩码上表中列出了两个相关的结构体：struct ifconf 和struct ifreq，要了解ioctl函数的具体运用，首先要了解这两个结构：struct ifconf{int ifc_len;union{__caddr_t ifcu_buf;struct ifreq *ifcu_req;} ifc_ifcu;};struct ifreq{# define IFHWADDRLEN 6# define IFNAMSIZ IF_NAMESIZEunion{char ifrn_name[IFNAMSIZ];} ifr_ifrn;union{struct sockaddr ifru_addr;struct sockaddr ifru_dstaddr;struct sockaddr ifru_broadaddr;struct sockaddr ifru_netmask;struct sockaddr ifru_hwaddr;short int ifru_flags;int ifru_ivalue;int ifru_mtu;struct ifmap ifru_map;char ifru_slave[IFNAMSIZ];char ifru_newname[IFNAMSIZ];__caddr_t ifru_data;} ifr_ifru;};struct ifconf的第二个元素ifc_ifcu是一个联合，是指向struct ifreq结构的地址，通常是一组struct ifreq结构空间（每一个描述一个接口），struct ifconf的第一个元素ifc_len描述了struct ifreq结构空间的大小；结构struct ifreq也有两个元素，第一个元素ifr_ifrn内含一个字符串，用来描述接口的名称，比如“eth0″、”wlan0”等，第二个元素是联合，比较复杂，用来描述套接口的地址结构。

0001-C语言如何获取ipv6地址
C语⾔如何获取ipv6地址written by whowin使⽤通常获取ipv4的IP地址的⽅法是⽆法获取ipv6地址的，本⽂介绍了使⽤C语⾔获取ipv6地址的三种⽅法，每种⽅法均给出了完整的源程序，本⽂所有实例在 ubuntu 20.04 下测试通过，gcc 版本 9.4.0。
1. ipv4的IP地址的获取⽅法不论是获取 ipv4 的 IP 地址还是 ipv6 的地址，应⽤程序都需要与内核通讯才可以完成；ioctl 是和内核通讯的⼀种常⽤⽅法，也是⽤来获取 ipv4 的 IP 地址的常⽤⽅法，下⾯代码演⽰了如何使⽤ioctl 来获取本机所有接⼝的 IP 地址：#include <stdio.h>#include <stdlib.h>#include <sys/ioctl.h>#include <linux/if.h>#include <arpa/inet.h>#include <sys/socket.h>int main() {int i=0;int sockfd;struct ifconf ifc;char buf[512] = {0};struct ifreq*ifr;ifc.ifc_len=512;ifc.ifc_buf=buf;if ((sockfd=socket(AF_INET, SOCK_DGRAM, 0)) <0) {perror("socket");return-1;}ioctl(sockfd, SIOCGIFCONF, &ifc);ifr= (struct ifreq*)buf;for (i= (ifc.ifc_len/sizeof(struct ifreq)); i>0; i--) {printf("%s: %s\n",ifr->ifr_name,inet_ntoa(((struct sockaddr_in*)&(ifr->ifr_addr))->sin_addr));ifr++;}}但是使⽤ ioctl ⽆法获取 ipv6 地址，即便我们建⽴⼀个 AF_INET6 的 socket，ioctl 仍然只返回 ipv4 的信息，我们可以试试下⾯代码；#include <stdio.h>#include <stdlib.h>图1：ioctl ⽆法获取ipv6地址这段程序在我的机器上的运⾏结果是这样的：我们看到，不管怎么折腾，返回的仍然只有 ipv4 的地址，所以我们需要⼀些其他的⽅法获得 ipv6 地址，下⾯介绍三种使⽤ C 语⾔获得 ipv6 地址的⽅法。
c#获得本地ip地址的三种方法
c#获得本地ip地址的三种⽅法⽹上有很多种⽅法可以获取到本地的IP地址。
⼀线常⽤的有这么些：枚举本地⽹卡using workInformation;using .Sockets;foreach (NetworkInterface netif in NetworkInterface.GetAllNetworkInterfaces().Where(a => a.SupportsMulticast).Where(a => a.OperationalStatus == OperationalStatus.Up).Where(a => workInterfaceType != NetworkInterfaceType.Loopback).Where(a => a.GetIPProperties().GetIPv4Properties() != null).Where(a => a.GetIPProperties().UnicastAddresses.Any(ua => ua.Address.AddressFamily == AddressFamily.InterNetwork)).Where(a => a.GetIPProperties().UnicastAddresses.Any(ua => ua.IsDnsEligible))){Console.WriteLine("Network Interface: {0}", );IPInterfaceProperties properties = netif.GetIPProperties();foreach (IPAddressInformation unicast in properties.UnicastAddresses)Console.WriteLine("\tUniCast: {0}", unicast.Address);}获得的信息⽐较全⾯，相当于⽹卡的信息都能获取，但是不能区分虚拟⽹卡（⽐如docker）。
