Hello Devid,

I have created the program as per your request. 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace Program
{
    classDisplayMessageForInput
    {
        publicstring GetInputResult()
        
        {
            Console.WriteLine("Please enter the string");
            returnConsole.ReadLine();
        }
 
    }
    classProgram
    {
        staticvoid Main(string[] args)
        {
            DisplayMessageForInput objDisplayInput = newDisplayMessageForInput();
            int  opt = 0;
            LinkedList<string> link1= newLinkedList<string>();
            do
            {
                Console.WriteLine("Main Menu");
                Console.WriteLine("1. Adding the new string at the last of the Linkedlist");
                Console.WriteLine("2. Adding the new string at the first of the Linkedlist");
                Console.WriteLine("3. Adding the string after which do want to insert");
                Console.WriteLine("4. Adding the string before which do want to insert");
                Console.WriteLine("5. Deleting the 1st element");
                Console.WriteLine("6. Deleting the last element");
                Console.WriteLine("7. DIsplay");
                Console.WriteLine("0. terminate the program");
 
                Console.Write("Enter the Operation you want to perform : ");
                opt = Convert.ToInt32(Console.ReadLine());
 
 
                switch (opt)
                {
                    case 1:
                    link1.AddLast(objDisplayInput.GetInputResult());
                        break;
                     case 2: link1.AddFirst(objDisplayInput.GetInputResult());
                        break; 
                    case 3:
                        Console.WriteLine("Enter the string after which do want to insert");
                        string element = Console.ReadLine();
                        LinkedListNode<string> node =link1.Find(element);
                        link1.AddAfter(node,objDisplayInput.GetInputResult());
                        break; 
                    case 4:
                        Console.WriteLine("Enter the string before which do want to insert");
                        string g = Console.ReadLine();
                        LinkedListNode<string> node1 = link1.Find(g);
                        link1.AddBefore(node1,objDisplayInput.GetInputResult());
                        break;
                  
                    case 5:
                        Console.WriteLine("Deleted element is {0} ",link1.First.Value);
                        link1.RemoveFirst();
                        break;
                    case 6:
                        Console.WriteLine("Deleted element is {0} ",link1.Last.Value);
                        link1.RemoveLast();
                        break;
                    case 7:
                        foreach (var linklist in link1)
                        {
                            Console.WriteLine("{0}", linklist);
                        }
                        break;
                    default:
                        if (opt != 0)
                            Console.WriteLine("Invalid option \n");
