如何獲取本地機器的IPv4和IPv6地址？

Question

我正在開發一個Windows應用程序，我需要找到本地機器的IPv4和IPv6地址。操作系統可以是XP或Windows 7

我得到了一個解決方案，讓MAC地址一樣，

string GetMACAddress() 
{ 
    var macAddr = 
     (
      from nic in NetworkInterface.GetAllNetworkInterfaces() 
      where nic.OperationalStatus == OperationalStatus.Up 
      select nic.GetPhysicalAddress().ToString() 
     ).FirstOrDefault(); 

    return macAddr.ToString(); 
} 

這在所有OS工作。

獲得適用於XP和WINDOWS 7的IPv4和IPv6地址的正確方法是什麼？

Answer 1

string strHostName = System.Net.Dns.GetHostName();; 
IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName); 
IPAddress[] addr = ipEntry.AddressList; 
Console.WriteLine(addr[addr.Length-1].ToString()); 
if (addr[0].AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6) 
      { 
       Console.WriteLine(addr[0].ToString()); //ipv6 
      }

這裏是我的方法只獲取所有的IPv4地址。

/// <summary> 
    /// Gets/Sets the IPAddress(s) of the computer which the client is running on. 
    /// If this isn't set then all IPAddresses which could be enumerated will be sent as 
    /// a comma separated list. 
    /// </summary> 
    public string IPAddress 
    { 
     set 
     { 
      _IPAddress = value; 
     } 
     get 
     { 
      string retVal = _IPAddress; 

      // If IPAddress isn't explicitly set then we enumerate all IP's on this machine. 
      if (_IPAddress == null) 
      { 
       // TODO: Only return ipaddresses that are for Ethernet Adapters 

       String strHostName = Dns.GetHostName(); 
       IPHostEntry ipEntry = Dns.GetHostEntry(strHostName); 
       IPAddress[] addr = ipEntry.AddressList; 

       List<string> validAddresses = new List<string>(); 

       // Loops through the addresses and creates a list of valid ones. 
       for (int i = 0; i < addr.Length; i++) 
       { 
        string currAddr = addr[i].ToString(); 
        if(IsValidIP(currAddr)) { 
         validAddresses.Add(currAddr); 
        } 
       } 

       for(int i=0; i<validAddresses.Count; i++) 
       { 
        retVal += validAddresses[i]; 
        if (i < validAddresses.Count - 1) 
        { 
         retVal += ","; 
        } 
       } 

       if (String.IsNullOrEmpty(retVal)) 
       { 
        retVal = String.Empty; 
       } 

      } 

      return retVal; 
     } 
    }

要得到所有的IP4和IP6地址，這裏是我的首選解決方案。請注意，它也會過濾環回IP地址，如127.0.0.1或：1

public static IEnumerable<IPAddress> GetIpAddress() 
     { 
      var host = Dns.GetHostEntry(Dns.GetHostName()); 
      return (from ip in host.AddressList where !IPAddress.IsLoopback(ip) select ip).ToList(); 
     }
