Try this (I'm assuming you want to display the MAC address in a textbox, say): private NetworkInterface[] nic; // make nic a private field so you only need to load the network interfaces once public MainWindow() { InitializeComponent(); nic = NetworkInterface.GetAllNetworkInterfaces(); // now assigning to private field foreach (var ni in nic) { comboBox.Items.Add(ni.Name); } comboBox.SelectedIndex = 0; } private void comboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) { int index = comboBox.SelectedIndex; if (index == -1) { textBox.Text = ""; return; } string mac = nic[index].GetPhysicalAddress().ToString(); textBox.Text = mac; }

using System . Management ; string query = "SELECT * FROM Win32_NetworkAdapterConfiguration" ; ManagementObjectSearcher moSearch = new ManagementObjectSearcher ( query ); ManagementObjectCollection moCollection = moSearch . Get (); // Every record in this collection is a network interface foreach ( ManagementObject mo in moCollection ) { // Do what you need to here.... } //u can do this as well.

UdpClient u = new UdpClient ( remoteAddress , 1 ); IPAddress localAddr = (( IPEndPoint ) u . Client . LocalEndPoint ). Address ; Now, if you want the NetworkInterface object you do something like: foreach ( NetworkInterface nic in NetworkInterface . GetAllNetworkInterfaces ()) { //Add it in Combo Box }
