Get the number of nodes contained in LinkedList in C#
To get the number of nodes contained in the LinkedList, the code is as follows −
Example
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"); list.AddLast("G"); list.AddLast("H"); list.AddLast("I"); list.AddLast("J"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("First Node = "+list.First.Value); list.Clear(); Console.WriteLine("Count of nodes (updated) = " + list.Count); } }
Output
This will produce the following output −
Count of nodes = 10 First Node = A Count of nodes (updated) = 0
Example
Let us see another example −
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { LinkedList<String> list1 = new LinkedList<String>(); list1.AddLast("One"); list1.AddLast("Two"); list1.AddLast("Three"); list1.AddLast("Four"); list1.AddLast("Five"); Console.WriteLine("Elements in LinkedList1..."); foreach (string res in list1) { Console.WriteLine(res); } LinkedList<String> list2 = new LinkedList<String>(); list2.AddLast("India"); list2.AddLast("US"); list2.AddLast("UK"); list2.AddLast("Canada"); list2.AddLast("Poland"); list2.AddLast("Netherlands"); Console.WriteLine("Elements in LinkedList2..."); foreach (string res in list2) { Console.WriteLine(res); } LinkedList<String> list3 = new LinkedList<String>(); Console.WriteLine("Count of nodes in LinkedList3 = "+list3.Count); list3 = list2; Console.WriteLine("Count of nodes in LinkedList3 (Updated) = "+list2.Count); Console.WriteLine("Is LinkedList3 equal to LinkedList2? = "+list3.Equals(list2)); } }
Output
This will produce the following output −
Elements in LinkedList1... One Two Three Four Five Elements in LinkedList2... India US UK Canada Poland Netherlands Count of nodes in LinkedList3 = 0 Count of nodes in LinkedList3 (Updated) = 6 Is LinkedList3 equal to LinkedList2? = True
