首先，设置一个带有节点的 LinkedList。
string [] students = {"Tim","Jack","Henry","David","Tom"};
LinkedList<string> list = new LinkedList<string>(students);
要在第一个位置添加节点，请使用 AddFirst() 方法。
list.AddFirst("Amit");
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);
}
// 添加节点
Console.WriteLine("LinkedList after adding a node at the first position...");
list.AddFirst("Amit");
foreach (var stu in list) {
Console.WriteLine(stu);
}
}
}
输出
Tim Jack Henry David Tom LinkedList after adding a node at the first position... Amit Tim Jack Henry David Tom
