How to get ip address or host name using c# .net?

In general, we are getting IP address by run command by type keyword ipconfig . And, if we execute this as Administrator Command Prompt then you will get the basic Network details like Host Name, IPAddress and Gateway.  

In this example we can achieve both byGetHostName() and Dns.GetHostByName(hostname) Method using the namespace System.Net.

using System.Net; 

class Program

    {
        static void Main(string[] args)
        {
            try
            {
                Console.WriteLine(GetIPAddress()); 
            }

            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
            Console.ReadLine();
        }

        private static string GetIPAddress()
        {
            string strHostName = null;
            strHostName = System.Net.Dns.GetHostName();
            string myIP = Dns.GetHostByName(strHostName).AddressList[0].ToString();
            return "Host Name: " + strHostName + "; IP Address: " + myIP;
         }

    }

 Output:

your Host

your Ip Address
