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


}
