Getting an enumerator that iterates through LinkedList in C#

CsharpServer Side ProgrammingProgramming

To get an enumerator that iterates through LinkedList, the code is as follows −

Example

 Live Demo

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("Elements in LinkedList... (Enumerator iterating through LinkedList)");
      LinkedList<string>.Enumerator demoEnum = list.GetEnumerator();
      while (demoEnum.MoveNext()) {
         string res = demoEnum.Current;
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Count of nodes = 10
Elements in LinkedList... (Enumerator iterating through LinkedList)
A
B
C
D
E
F
G
H
I
J

Example

Let us see another example −

 Live Demo

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... (Enumerator iterating through LinkedList2)");
      LinkedList<string>.Enumerator demoEnum = list2.GetEnumerator();
      while (demoEnum.MoveNext()) {
         string res = demoEnum.Current;
         Console.WriteLine(res);
      }
      LinkedList<string> list3 = new LinkedList<string>();
      list3 = list2;
      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... (Enumerator iterating through LinkedList2)
India
US
UK
Canada
Poland
Netherlands
Is LinkedList3 equal to LinkedList2? = True
