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

Here a sample code to reverse a linked list.

using System;

class Program
{
    static void Main(string[] args)
    {
        LinkItem item = generateLinkList(5);
        printLinkList(item);
        Console.WriteLine("Reversing the list ...");
        LinkItem newItem = reverseLinkList(item);
        printLinkList(newItem);
        Console.ReadLine();
    }

    static public LinkItem generateLinkList(int total)
    {
        LinkItem item = new LinkItem();
        for (int number = total; number >=1; number--)
        {
            item = new LinkItem
            {
                name = string.Format("I am the link item number {0}.", number),
                next = (number == total) ? null : item
            };
        }
        return item;
    }

    static public void printLinkList(LinkItem item)
    {
        while (item != null)
        {
            Console.WriteLine(item.name);
            item = item.next;
        }
    }

    static public LinkItem reverseLinkList(LinkItem item)
    {
        LinkItem newItem = new LinkItem
        {
            name = item.name,
            next = null
        };

        while (item.next != null)
        {
            newItem = new LinkItem
            {
                name = item.next.name,
                next = newItem
            };

            item = item.next;
        }

        return newItem;
    }
}

class LinkItem
{
    public string name;
    public LinkItem next;
}
