In this blog I am demonstrating you that how to retrieve basic network device information such as network id, network name and description using c#.

To make this program you need to import  System.Net.NetworkInformation namespace.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.NetworkInformation;
namespace NetworkInformationDemo1
{
    class Program
    {
        static void Main(string[] args)
        {
            //Retrive all network interface using GetAllNetworkInterface() method off NetworkInterface class.
            NetworkInterface [] niArr = NetworkInterface.GetAllNetworkInterfaces();
            Console.WriteLine("Retriving basic information of network.\n\n");
            //Display all information of NetworkInterface using foreach loop.
            foreach(NetworkInterface tempNetworkInterface in niArr)
            {
                Console.WriteLine("Network Discription  :  " + tempNetworkInterface.Description);
                Console.WriteLine("Network ID  :  " + tempNetworkInterface.Id);
                Console.WriteLine("Network Name  :  " + tempNetworkInterface.Name);
                Console.WriteLine("Network interface type  :  " + tempNetworkInterface.NetworkInterfaceType.ToString());
                Console.WriteLine("Network Operational Status   :   " + tempNetworkInterface.OperationalStatus.ToString());
                Console.WriteLine("Network Spped   :   " + tempNetworkInterface.Speed);
                Console.WriteLine("Support Multicast   :   " + tempNetworkInterface.SupportsMulticast);
                Console.WriteLine();
            }
        }
    }
}

Output of the following code snippet is as follows:
