C#获取本机IP搜集整理几种方法
print?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());
}
}
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
[csharp]
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();
}
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
[csharp]
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：
<div 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></div>
解析这段就行
*/
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：
<div 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></div>
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;
[csharp] view plaincopyprint?private void GetIP2()
{
string stringMAC = "";
string stringIP = "";
ManagementClass managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection managementObjectCollection = managementClass.GetInstances();
foreach(ManagementObject managementObject in managementObjectCollection)
{
