Để thêm nút hoặc giá trị mới vào đầu LinkedList, mã như sau -
Ví dụ
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("\nWe 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); } } }

Điều này sẽ tạo ra kết quả sau−
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
Ví dụ
Bây giờ chúng ta hãy xem một ví dụ khác -
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("\nWe 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); } } }
Đầu ra
Điều này sẽ tạo ra kết quả sau -
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
