Unix/Linux WhoAmI command in C#

In Linux we have an elegant and quick command to display the currently logged on user. It is called 'WhoAmI'. You can check out the manpage of this command here. I just thought would create a quick and simple C# port of the same and share it with interested users.

The code is a very simple and straight-forward console application and I hope it is also useful for beginners to learn the programming language with ease and fun.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Security.Principal;

namespace LavanyaDeepak.UnixCommands

{

    class WhoAmI

    {

        static void Main(string[] args)

        {

            Console.Clear();

            try

            {

                Console.ForegroundColor = ConsoleColor.Green;

                WindowsIdentity objWindowsIdentity = WindowsIdentity.GetCurrent();

                Console.WriteLine(string.Format("You are currently logged on as {0}", objWindowsIdentity.Name));

            }

            catch (System.Security.SecurityException objSecurityException)

            {

                Console.ForegroundColor = ConsoleColor.DarkRed;

                Console.WriteLine(string.Format("Could not fetch currently logged on user. There was a security error: ", objSecurityException.Message));

            }

            catch (System.Exception objGeneralException)

            {

                Console.ForegroundColor = ConsoleColor.Red;

                Console.WriteLine(string.Format("Could not fetch currently logged on user. There was a general error: ", objGeneralException.Message));

            }

            Console.ReadKey();

        }

    }

}
