How do you get the index of a number in a linked list?

Question

I have a linked list constructed as follows:

LinkedList linked = new LinkedList();
var array = new int[] { 23, 55, 64, 65 };
foreach (         


        

Answer 1

int index = linked.Select((item, inx) => new { item, inx })
                  .First(x=> x.item == 64).inx;
