Two code snippets for inspiration:
using System;
using System.IO;
using System.Diagnostics;
namespace E
{
public class Program
{
public static void Main(string[] args)
{
string fnm = @"c:\work\tmp_file";
Process.Start("cmd", "/c ipconfig/all > " + fnm);
using(StreamReader sr = new StreamReader(fnm))
{
string line;
while((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
File.Delete(fnm);
Console.ReadKey();
}
}
}
using System;
using System.Net.NetworkInformation;
namespace E
{
public class Program
{
public static void Main(string[] args)
{
foreach(NetworkInterface ni in
NetworkInterface.GetAllNetworkInterfaces())
{
Console.WriteLine("name=" + ni.Name);
foreach(UnicastIPAddressInformation addr in
ni.GetIPProperties().UnicastAddresses)
{
Console.WriteLine("addr=" + addr.Address.ToString());
}
foreach(GatewayIPAddressInformation gw in
ni.GetIPProperties().GatewayAddresses)
{
Console.WriteLine("gw=" + gw.Address.ToString());
}
}
Console.ReadKey();
}
}
}
