[英]How to get IPv4 and IPv6 address of local machine?
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。
我得到了一個獲取MAC地址的解決方案,
string GetMACAddress()
{
var macAddr =
(
from nic in NetworkInterface.GetAllNetworkInterfaces()
where nic.OperationalStatus == OperationalStatus.Up
select nic.GetPhysicalAddress().ToString()
).FirstOrDefault();
return macAddr.ToString();
}
這適用於所有操作系統。
獲取適用於XP和WINDOWS 7的IPv4和IPv6地址的正確方法是什么?
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
}
要獲得所有IP4和IP6地址,這是我的首選解決方案。 請注意,它還會過濾環回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();
}
這是我獲取所有IPv4地址的方法。
/// <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;
}
}
