推荐答案

我不知道它对你有用吗但是

您将获得使用System.Net.NetworkInformation的网络中系统的所有IP地址

i dont know is it useful for you but
you will get all the ip addresses of systems which are in network

using System.Net.NetworkInformation;
using System.Threading;
using System.Diagnostics;
using System.Collections.Generic;
using System;
 
namespace ConsoleApplication1
{
    class localipaddresses
    {
        private static List<ping> pingers = new List<ping>();
        private static int instances = 0;
 
        private static object @lock = new object();
 
        private static int result = 0;
        private static int timeOut = 250;
 
        private static int ttl = 5;
 
        public static void Main()
        {
            string baseIP = "192.168.0.";
 
            Console.WriteLine("Pinging 255 destinations of D-class in {0}*", baseIP);
 
            CreatePingers(255);
 
            PingOptions po = new PingOptions(ttl, true);
            System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
            byte[] data = enc.GetBytes("abababababababababababababababab");
 
            SpinWait wait = new SpinWait();
            int cnt = 1;
 
            Stopwatch watch = Stopwatch.StartNew();
 
            foreach (Ping p in pingers)
            {
                lock (@lock)
                {
                    instances += 1;
                }
 
                p.SendAsync(string.Concat(baseIP, cnt.ToString()), timeOut, data, po);
                cnt += 1;
            }
 
            while (instances > 0)
            {
                wait.SpinOnce();
            }
 
            watch.Stop();
 
            DestroyPingers();
 
            Console.WriteLine("Finished in {0}. Found {1} active IP-addresses.", watch.Elapsed.ToString(), result);
            Console.ReadKey();
 
        }
 
        public static void Ping_completed(object s, PingCompletedEventArgs e)
        {
            lock (@lock)
            {
                instances -= 1;
            }
 
            if (e.Reply.Status == IPStatus.Success)
            {
                Console.WriteLine(string.Concat("Active IP: ", e.Reply.Address.ToString()));
                result += 1;
            }
            else
            {
                //Console.WriteLine(String.Concat("Non-active IP: ", e.Reply.Address.ToString()))
            }
        }
 
        private static void CreatePingers(int cnt)
        {
            for (int i = 1; i <= cnt; i++)
            {
                Ping p = new Ping();
                p.PingCompleted += Ping_completed;
                pingers.Add(p);
            }
        }
 
        private static void DestroyPingers()
        {
            foreach (Ping p in pingers)
            {
                p.PingCompleted -= Ping_completed;
                p.Dispose();
            }
            pingers.Clear();
        }
    }
}
