Hi !
I'm developing a project in which i connect two computers with a tcplistener class and a tcpclient class, but the tcpclient requires an ip , since it changes a lot , i would like to access the computer with the tcpserver class using the name of the computer or any other method, is this possible? I want to connect them without any wire and it is not necessary to use those classes, i just point the way I'm doing it.
any recommendation is accepted =)
Thanks

If you know the PC name, then:

using System.Net;
...
      string strHostName = "MYPCNAME";
      IPHostEntry ipEntry = Dns.GetHostByName (strHostName);
      IPAddress [] addr = ipEntry.AddressList;
      IPAddress ip = addr[0];
      Console.WriteLine("{0}", ip);

This is correct, but redundant, because TcpClient can also accept Dns name instead of IP. Please see my answer.

You can also construct TpcClient by DNS name of the remote computer running TcpListener. See the constructor System.Net.Sockets.TcpClient(string hostname, int port). A computer can have more then one IP, and only one of them is associated with a given DNS entry, so this is the only reliable association.

True, and, on a Windows network, DNS resolution includes the computer name as seen in net view.

Agree. Thank you, Bob.
