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:

CSharp

// 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:

CSharp

// 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.
