Write a program that include a method that returns the sum of all the elements of a linked list of integers. allow the user to enter the integers to be added to your linked list from the console (max of 10 integers). test your program and display your integers and the sum results.

static void Main(string[] args)

       {

           //declare a blank linked list

           LinkedList<int> numList = new LinkedList<int>();

           Console.WriteLine("Enter the Numbers");

           //check if the size of the linkedlist is 10

           while(numList.Count < 10)

           {

               //read the input supplied by the user

               string val = Console.ReadLine();

               //check if the input is integer

               if(int.TryParse(val, out _) == false)

               {

                   //if not integer, display error message and prompt for new number

                   Console.WriteLine("Invalid number");

                   continue;

               }

               //add the inputted number to the linkedlist

               numList.AddLast(int.Parse(val));

           }

           //call the method for linkedlist sum and display it

           Console.WriteLine(SumLinkedList(numList));

           Console.Read();

       }

       //method for linkedlist summation

       private static int SumLinkedList(LinkedList<int> val)

       {

           //declare sum as zero

           int sum = 0;

           //loop through the linkedlist to display the num and sum all numbers

           foreach(int item in val)

           {

               Console.Write(item + " ");

               sum += item;

           }

           return sum;

       }

   }
