hi to all,

I am Looking to scan a network connected computer to my system along with all subnet mask created on that IP address in web application,

I have a code that give me a list in console application using Ping method but that method does not work in web application, so need some help.

Here is console Code

class Program
    {
        
        static int upCount = 0;
        static object lockObj = new object();
        const bool resolveNames = true;

        static void Main(string[] args)
        {
        
            Stopwatch sw = new Stopwatch();
            sw.Start();
            string ipBase = "192.168.1.";
            for (int i = 1; i < 255; i++)
            {
                string ip = ipBase + i.ToString();

                Ping p = new Ping();
                p.PingCompleted += new PingCompletedEventHandler(p_PingCompleted);
        
                p.SendAsync(ip, 100, ip);
            }
        
            sw.Stop();
            TimeSpan span = new TimeSpan(sw.ElapsedTicks);
            Console.WriteLine("Took {0} milliseconds. {1} hosts active.", sw.ElapsedMilliseconds, upCount);
            Console.ReadLine();
        }

        static void p_PingCompleted(object sender, PingCompletedEventArgs e)
        {
            string ip = (string)e.UserState;
            if (e.Reply != null && e.Reply.Status == IPStatus.Success)
            {
                if (resolveNames)
                {
                    string name;
                    try
                    {
                        IPHostEntry hostEntry = Dns.GetHostEntry(ip);
                        name = hostEntry.HostName;
                    }
                    catch (SocketException ex)
                    {
                        name = "?";
                    }
                    Console.WriteLine("{0} ({1}) is up: ({2} ms)", ip, name, e.Reply.RoundtripTime);
                }
                else
                {
                    Console.WriteLine("{0} is up: ({1} ms)", ip, e.Reply.RoundtripTime);
                }
                lock (lockObj)
                {
                    upCount++;
                }
            }
            else if (e.Reply == null)
            {
                Console.WriteLine("Pinging {0} failed. (Null Reply object?)", ip);
            }

        }
    }

Thanks
