c#链表创建的方法是什么

using System;using System.Collections.Generic;class Program{    static void Main()    {        LinkedList<int> linkedList = new LinkedList<int>();        linkedList.AddLast(1);        linkedList.AddLast(2);        linkedList.AddLast(3);                foreach (var item in linkedList)        {            Console.WriteLine(item);        }    }}

using System;class Node{    public int data;    public Node next;    public Node(int data)    {        this.data = data;        this.next = null;    }}class LinkedList{    public Node head;    public void Add(int data)    {        Node newNode = new Node(data);        if (head == null)        {            head = newNode;        }        else        {            Node current = head;            while (current.next != null)            {                current = current.next;            }            current.next = newNode;        }    }    public void Display()    {        Node current = head;        while (current != null)        {            Console.WriteLine(current.data);            current = current.next;        }    }}class Program{    static void Main()    {        LinkedList linkedList = new LinkedList();        linkedList.Add(1);        linkedList.Add(2);        linkedList.Add(3);                linkedList.Display();    }}

无论采用哪种方法，都可以通过添加节点、删除节点等操作来操作链表。
