Answer:
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;
}
}
