[C#]取得網卡的IPV6位置

最近有個需求是要取得本地端的IPV6位置，若用IPHostEntry去取AddressList，回傳的IP位置內沒有IPV6的位置資訊，因此換個方法改透過System.Net.NetworkInformation.NetworkInterfaceType下去取所有的網卡資訊，再從網卡資訊內去擷取IPV6的位置資訊，這邊隨筆將之記錄一下。


        private static IEnumerable<String> GetLocalIPV6IP()
        {
            return (from adapter in NetworkInterface.GetAllNetworkInterfaces()                   
                    where adapter .NetworkInterfaceType ==  NetworkInterfaceType.Ethernet 
                    from AddressInfo in adapter.GetIPProperties().UnicastAddresses.OfType<UnicastIPAddressInformation>()
                    where AddressInfo.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6                    
                    let ipAddress = AddressInfo.Address.ToString()
                    select ipAddress);
        }

完整範例如下：


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.NetworkInformation;

namespace ConsoleApplication13
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (var ip in GetLocalIPV6IP())
            {
                Console.WriteLine(ip);
            }
        }

        private static IEnumerable<String> GetLocalIPV6IP()
        {
            return (from adapter in NetworkInterface.GetAllNetworkInterfaces()                   
                    where adapter .NetworkInterfaceType ==  NetworkInterfaceType.Ethernet 
                    from AddressInfo in adapter.GetIPProperties().UnicastAddresses.OfType<UnicastIPAddressInformation>()
                    where AddressInfo.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6                    
                    let ipAddress = AddressInfo.Address.ToString()
                    select ipAddress);
        }
    }
}
