C# | Check if two SortedSet<T> objects are equal

Equals(Object) Method which is inherited from the Object class is used to check if a specified SortedSet<T> object is equal to another SortedSet<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 SortedSet object
// is equal to another SortedSet object
using System;
using System.Collections.Generic;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // Creating a SortedSet of strings
        SortedSet<string> mySet = new SortedSet<string>();

        // Inserting elements in SortedSet
        mySet.Add("DS");
        mySet.Add("C++");
        mySet.Add("Java");
        mySet.Add("JavaScript");

        // Checking whether mySet is
        // equal to itself or not
        Console.WriteLine(mySet.Equals(mySet));
    }
}

Output:

True

Example 2:

// C# program to if a SortedSet object
// is equal to another SortedSet object
using System;
using System.Collections.Generic;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // Creating a SortedSet of strings
        SortedSet<string> mySet1 = new SortedSet<string>();

        // Inserting elements in SortedSet
        mySet1.Add("GeeksforGeeks");
        mySet1.Add("Noida");
        mySet1.Add("Data Structure");
        mySet1.Add("Noida");

        // Creating a SortedSet of integers
        SortedSet<int> mySet2 = new SortedSet<int>();

        // Inserting elements in SortedSet
        for (int i = 0; i < 5; i++) {
            mySet2.Add(i * 2);
        }

        // Checking whether mySet1 is
        // equal to mySet2 or not
        Console.WriteLine(mySet1.Equals(mySet2));

        // Creating a SortedSet of integers
        SortedSet<int> mySet3 = new SortedSet<int>();

        // Assigning mySet2 to mySet3
        mySet3 = mySet2;

        // Checking whether mySet3 is
        // equal to mySet2 or not
        Console.WriteLine(mySet3.Equals(mySet2));
    }
}

Output:

False
True

Note: If the current instance is a reference type, the Equals(Object) method checks for reference equality.
