C# | Check if two LinkedList<T> objects are equal
Last Updated :

Equals(Object) Method which is inherited from the Object class is used to check if a specified
LinkedList<T> object is equal to another LinkedList<T> object or not.
Syntax:
public virtual bool Equals (object obj);
Here,
obj is the object which is to be compared with the current object.
Return Value: This method return
true if the specified object is equal to the current object otherwise it returns
false.
Below programs illustrate the use of above-discussed method:
Example 1:
CSharp
// C# program to if a LinkedList object
// is equal to another LinkedList object
using System;
using System.Collections.Generic;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a LinkedList of Strings
LinkedList<String> myList1 = new LinkedList<String>();
// Adding nodes in LinkedList
myList1.AddLast("Geeks");
myList1.AddLast("for");
myList1.AddLast("Data Structures");
myList1.AddLast("Noida");
// Checking whether myList1 is
// equal to itself or not
Console.WriteLine(myList1.Equals(myList1));
}
}
Example 2:
CSharp
// C# program to if a LinkedList object
// is equal to another LinkedList object
using System;
using System.Collections.Generic;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a LinkedList of Strings
LinkedList<String> myList1 = new LinkedList<String>();
// Adding nodes in LinkedList
myList1.AddLast("C");
myList1.AddLast("C++");
myList1.AddLast("Java");
myList1.AddLast("C#");
// Creating a LinkedList of Integers
LinkedList<int> myList2 = new LinkedList<int>();
// Adding nodes in LinkedList
myList2.AddLast(2);
myList2.AddLast(4);
myList2.AddLast(6);
myList2.AddLast(8);
// Checking whether myList1 is
// equal to myList2 or not
Console.WriteLine(myList1.Equals(myList2));
// Creating a LinkedList of Integers
LinkedList<int> myList3 = new LinkedList<int>();
// Assigning myList2 to myList3
myList3 = myList2;
// Checking whether myList3 is
// equal to myList2 or not
Console.WriteLine(myList3.Equals(myList2));
}
}
Note: If the current instance is a reference type, the
Equals(Object) method checks for reference equality.
