本文實例講述了C#完成的簡略鏈表類。分享給年夜家供年夜家參考。詳細以下:
1、關於C#鏈表
C#鏈表可用類LinkedList來寄存。本文中的類MyLinkedList只是完成了該類的最根本的功效。C#中沒有指針,但由於C#中類在賦值時傳遞的是地址,是以依然可以應用這點制造一個鏈表。
2、結點類Node和鏈表類MyLinkedList代碼
/// <summary> /// 鏈表結點 /// </summary> class Node { //結點數據,前後結點 public object Data; public Node PreviousNode; public Node NextNode; //結構函數 public Node(object data = null) { Data = data; PreviousNode = null; NextNode = null; } //輸入結點信息 public override string ToString() { return Data.ToString(); } } /// <summary> /// 鏈表類 /// </summary> class MyLinkedList { //首結點、尾結點 public Node First; public Node Last; //下一個結點、上一個結點 public Node NextNode(Node n) { return n.NextNode; } public Node PreviousNode(Node n) { return n.PreviousNode; } //結點總數 public int Count; //結構函數 public MyLinkedList() { this.First = null; this.Last = null; Count = 0; } /// <summary> /// 在結點node1以後增長結點node2,假如沒有該結點則在最初增長 /// </summary> /// <param name="node1">結點1</param> /// <param name="node2">結點2</param> public void AddAfter(Node node1, Node node2) { //鏈表為空的情形 if (First == null) { Console.WriteLine("Linked-list is null! Can not find node1(" + node1 + ")"); return; } Node temp = First; do { if (temp.Data.Equals(node1.Data)) { //假如node1是尾結點 if (node1.NextNode == null) { node2.NextNode = null; node2.PreviousNode = node1; node1.NextNode = node2; } else //假如node1不是尾結點 { node2.NextNode = node1.NextNode; node2.PreviousNode = node1; node2.NextNode.PreviousNode = node2; node1.NextNode = node2; ; } Count++; Console.WriteLine("Node(" + node2 + "): Add Complete!"); return; } temp = temp.NextNode; } while (temp != null); Console.WriteLine("Can not find node(" + node1 + "), Misson defeat"); } /// <summary> /// 在鏈表尾部增長結點 /// </summary> public void AddLast(Node node) { //鏈表為空的情形 if (this.First == null) { node.NextNode = null; node.PreviousNode = null; this.First = node; this.Last = node; } else //鏈表不為空的情形 { Node temp = First; while(temp.NextNode != null) { temp = temp.NextNode; } temp.NextNode = node; node.PreviousNode = temp; Last = node; } Count++; Console.WriteLine("Node(" + node + "): Add Complete!"); } /// <summary> /// 刪除指定結點 /// </summary> /// <param name="node">被刪除結點</param> public void Delete(Node node) { if (Count == 0) { Console.WriteLine("Can not find node(" + node + ")"); return; } Node temp = First; do { //假如數據部門婚配,則刪去該結點 if (temp.Data.Equals(node.Data)) { //temp是尾結點 if (temp.NextNode == null) { temp.PreviousNode.NextNode = null; temp = null; } else //temp不是尾結點 { temp.PreviousNode.NextNode = temp.NextNode; temp.NextNode.PreviousNode = temp.PreviousNode; temp = null; } Count--; Console.WriteLine("Node(" + node + "): Delete Complete!"); return; } temp = temp.NextNode; } while (temp != null); Console.WriteLine("Can not find node(" + node + "), Misson defeat"); } /// <summary> /// 修正結點值 /// </summary> /// <param name="node">被修正結點</param> /// <param name="value">結點值</param> public void Modify(Node node, object value) { if (Count == 0) { Console.WriteLine("Can not find node(" + node + ")"); return; } Node temp = First; do { if (temp.Data.Equals(node.Data)) { Console.WriteLine("Node: " + temp.Data + " → " + value.ToString()); temp.Data = value; return; } temp = temp.NextNode; } while (temp != null); } /// <summary> /// 打印鏈表 /// </summary> public void Print() { if (First == null) { Console.WriteLine("No nodes in this linked-list."); return; } else { Console.WriteLine("Print the linked-list..."); Node temp = First; do { Console.WriteLine(temp.ToString()); temp = temp.NextNode; } while (temp != null); Console.WriteLine("Mission Complete!"); } } }
3、Main函數的挪用示例
static void Main(string[] args) { MyLinkedList ll = new MyLinkedList(); //添加三個結點 1 2(在1後) 3(在2後) Node n1 = new Node("node1"); Node n2 = new Node("node2"); Node n3 = new Node("node3"); ll.AddLast(n1); ll.AddLast(n2); ll.AddLast(n3); //添加三個結點 1.5(在1後) 2.5(在2後) 3.5(在3後) Node n1dot5 = new Node("node1dot5"); Node n2dot5 = new Node("node2dot5"); Node n3dot5 = new Node("node3dot5"); ll.AddAfter(n1, n1dot5); ll.AddAfter(n2, n2dot5); ll.AddAfter(n3, n3dot5); Console.WriteLine("========================"); //打印鏈表 ll.Print(); Console.WriteLine("========================"); //刪除結點 2 和 3,將結點 2.5 的值改成 "ThisNodeIsModified!" ll.Delete(n2); ll.Delete(n3); ll.Modify(n2dot5, "ThisNodeIsModified!"); Console.WriteLine("========================"); //打印鏈表 ll.Print(); Console.ReadLine(); }
