如题 代码如下 public string getIP() //获取IP
{
string HostName = Dns.GetHostName(); //得到主机名
IPHostEntry IpEntry = Dns.GetHostEntry(HostName); //得到主机IP
string strIPAddr = IpEntry.AddressList[0].ToString();
IPAddress ipp= IPAddress.Parse(strIPAddr);
return (ipp.ToString());
}我得到的结果为fe80::49d:8fbf:ca5e:d1cd%12求各位高人怎么把它变成ipv4的地址呢？好像我调试的时候看到socket没有ipv6支持啊
首先：ipv6是在Vista，或者Win7中获取的，XP中没有ipv6;然后：不能把ipv6变成ipv4，但是你可以直接获取ipv4的值。下面是我写的一个获取ipv6和ipv4的类。你可以直接把它编译成DLL文件，以后要使用ipv4,或者ipv6的时候，就可以直接调用这个动态链接库。-------------------------------------------------------------------------------------------------------------------------------------
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;using System.Windows.Forms;
namespace GetLocalIP{ public class GetIP { private IPAddress IPv4 , IPv6; public GetIP()//构造函数。 { getAllIP(); } private void getAllIP() { IPAddress [] ipList= Dns.GetHostAddresses(Dns.GetHostName()); foreach (IPAddress ip in ipList) { //获得IPv4 if (ip.AddressFamily == AddressFamily.InterNetwork) IPv4 = ip; //获得IPv6 if (ip.AddressFamily == AddressFamily.InterNetworkV6) IPv6 = ip; } } public IPAddress GetLocalIPv4()//通过这个public函数获取ipv4 { try { if (IPv4 != null) return IPv4; else return null; } catch (Exception error) { MessageBox.Show(" GetLocalIpv4 Error: " + error.Message); return null; } } public IPAddress GetLocalIPv6()//通过这个public函数获取ipv6 { try { if (IPv6 != null) return IPv6; else return null; } catch (Exception error) { MessageBox.Show(" GetLocalIpv6 Error: " + error.Message); return null; } } }}
---------------------------用法：首先你要添加这个动态链接库.直到可以使用该类。。
GetIP getLocalIP = new GetIP();IPAddress ipv4 = getLocalIP.GetLocalIPv4();IPAddress ipv6 = getLocalIP.GetLocalIPv6();----------------------------------------------------------------------当然如果你仅仅需要获得ipv4的值的话。只需要这样就可以了。首先获取所有的Ip地址，然后从中选择ipv4.
IPAddress IPv4; IPAddress [] ipList= Dns.GetHostAddresses(Dns.GetHostName()); foreach (IPAddress ip in ipList) { //获得IPv4 if (ip.AddressFamily == AddressFamily.InterNetwork) IPv4 = ip; }}
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;using System.Windows.Forms;
namespace GetLocalIP{ public class GetIP { private IPAddress IPv4 , IPv6; public GetIP()//构造函数。 { getAllIP(); } private void getAllIP() { IPAddress [] ipList= Dns.GetHostAddresses(Dns.GetHostName()); foreach (IPAddress ip in ipList) { //获得IPv4 if (ip.AddressFamily == AddressFamily.InterNetwork) IPv4 = ip; //获得IPv6 if (ip.AddressFamily == AddressFamily.InterNetworkV6) IPv6 = ip; } } public IPAddress GetLocalIPv4()//通过这个public函数获取ipv4 { try { if (IPv4 != null) return IPv4; else return null; } catch (Exception error) { MessageBox.Show(" GetLocalIpv4 Error: " + error.Message); return null; } } public IPAddress GetLocalIPv6()//通过这个public函数获取ipv6 { try { if (IPv6 != null) return IPv6; else return null; } catch (Exception error) { MessageBox.Show(" GetLocalIpv6 Error: " + error.Message); return null; } } }}
