C# 程序在链接列表中的给定节点之前添加一个节点

声明一个 LinkedList 并向其中添加节点。
string [] students = {"Tim","Jack","Henry","David","Tom"};
LinkedList<string> list = new LinkedList<string>(students);
让我们添加一个新节点。
var newNode = list.AddLast("Kevin");
现在，要在给定节点之前添加节点，请使用 AddBefore() 方法。
list.AddBefore(newNode, "Matt");
现在让我们看看完整的代码。
示例
using System;
using System.Collections.Generic;
class Demo {
static void Main() {
string [] students = {"Tim","Jack","Henry","David","Tom"};
LinkedList<string> list = new LinkedList<string>(students);
foreach (var stu in list) {
Console.WriteLine(stu);
}
// 在末尾添加一个节点
var newNode = list.AddLast("Kevin");
// 在上面添加的节点之前添加一个新节点
list.AddBefore(newNode, "Matt");
Console.WriteLine("LinkedList after adding new nodes...");
foreach (var stu in list) {
Console.WriteLine(stu);
}
}
}
输出
Tim Jack Henry David Tom LinkedList after adding new nodes... Tim Jack Henry David Tom Matt Kevin
