Is It possible to Get list of IP address connected in LAN,in C# without using win32 API library.?

You can use System.Net. NetworkInformation. Ping to ping every IP in your subnet if you get a response there is a machine using that ip.

If you don't get a response that ip is available, or the machine is ignoring pings.

You can use the NetworkInterface object to get all the machines network interfaces.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
