Reversing single linked list in C#

Question

I am trying to reverse a linked list. This is the code I have come up with:

 public static void Reverse(ref Node root)
 {
      Node tmp = root;
      Node n

This performed pretty well on Leetcode.

public ListNode ReverseList(ListNode head) {

        ListNode previous = null;
        ListNode current = head; 
        while(current != null) {
            ListNode nextTemp = current.next;
            current.next = previous;
            previous = current;
            current = nextTemp;
        }

        return previous;
    }
