Check if two LinkedList objects are equal in C#
To check if two LinkedList objects are equal, the code is as follows −
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>();
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... India US UK Canada Poland Netherlands Is LinkedList3 equal to LinkedList2? = True
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);
}
Console.WriteLine("Is LinkedList2 equal to LinkedList1? = "+list2.Equals(list1));
}
}Output
This will produce the following output −
Elements in LinkedList1... One Two Three Four Five Elements in LinkedList2... India US UK Canada Poland Netherlands Is LinkedList2 equal to LinkedList1? = False
