C# | Check if two LinkedList<T> objects are equal
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:
// 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)); } } |
True
Example 2:
// 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)); } } |
False True
Note: If the current instance is a reference type, the Equals(Object) method checks for reference equality.
