法律研究在 C# 中向链表开头添加新节点或值
若要在链表的开头添加新节点或值，代码如下所示 −
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
LinkedList<string> list = new LinkedList<string>();
list.AddLast("A");
list.AddLast("B");
list.AddLast("C");
list.AddLast("D");
list.AddLast("E");
list.AddLast("F");
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList...");
foreach (string res in list){
Console.WriteLine(res);
}
list.AddLast("G");
list.AddLast("H");
list.AddLast("I");
Console.WriteLine("Count of nodes...UPDATED = " + list.Count);
Console.WriteLine("Elements in LinkedList...UPDATED");
foreach (string res in list){
Console.WriteLine(res);
}
list.AddFirst("AA");
Console.WriteLine("
We added a node in the beginning...");
Console.WriteLine("Count of nodes...UPDATED = " + list.Count);
Console.WriteLine("Elements in LinkedList...UPDATED");
foreach (string res in list){
Console.WriteLine(res);
}
}
}输出
这将产生以下输出 −
Count of nodes = 6 Elements in LinkedList... A B C D E F Count of nodes...UPDATED = 9 Elements in LinkedList...UPDATED A B C D E F G H I We added a node in the beginning... Count of nodes...UPDATED = 10 Elements in LinkedList...UPDATED AA A B C D E F G H I
示例
现在让我们看另一个示例 −
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
LinkedList<int> list = new LinkedList<int>();
list.AddLast(100);
list.AddLast(200);
list.AddLast(300);
list.AddLast(400);
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList...");
foreach (int res in list){
Console.WriteLine(res);
}
list.AddFirst(500);
list.AddFirst(600);
Console.WriteLine("
We added a node in the beginning...");
Console.WriteLine("Count of nodes...UPDATED = " + list.Count);
Console.WriteLine("Elements in LinkedList...UPDATED");
foreach (int res in list){
Console.WriteLine(res);
}
}
}输出
这将产生以下输出 −
Count of nodes = 4 Elements in LinkedList... 100 200 300 400 We added a node in the beginning... Count of nodes...UPDATED = 6 Elements in LinkedList...UPDATED 600 500 100 200 300 400
