Güzel bir örnek oldu basit ve hızlı..
public class PortScanner
{
public List<int> ActivePorts = new List<int>();
public List<int> InactiveReports = new List<int>();
public void Scan(string IP, int startPort, int endPort)
{
Socket Sock = null;
for (int Port = startPort; Port <= endPort; Port++)
{
try
{
Sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
Sock.Connect(IP, Port);
ActivePorts.Add(Port);
}
catch (SocketException ex)
{
InactiveReports.Add(Port);
}
finally
{
if (Sock!=null)
{
if (Sock.Connected)
Sock.Disconnect(false);
Sock.Close();
}
}
}
}
}
