C# | Check if SortedSet and the specified collection contain the same elements

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet.SetEquals(IEnumerable) Method is used to check whether the SortedSet and the specified collection contain the same elements.

Properties:

• In C#, SortedSet class can be used to store, remove or view elements.
• It maintains ascending order and does not store duplicate elements.
• It is suggested to use SortedSet class if you have to store unique elements and maintain ascending order.

Syntax:

mySortedSet1.SetEquals(mySortedSet2);

Here, mySortedSet1 and mySortedSet2 are two SortedSet.

Return Value: The function returns True if mySortedSet1 and mySortedSet2 are equal, else returns False.

Exception: This method will give ArgumentNullException if the SortedSet is null.

Example 1:

// C# code to Check if SortedSet
// and the specified collection
// contain the same elements
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of integers
        SortedSet<int> mySortedSet1 = new SortedSet<int>();

        // adding elements in mySortedSet1
        mySortedSet1.Add(1);
        mySortedSet1.Add(2);
        mySortedSet1.Add(3);
        mySortedSet1.Add(4);
        mySortedSet1.Add(5);

        // Creating a SortedSet of integers
        SortedSet<int> mySortedSet2 = new SortedSet<int>();

        // adding elements in mySortedSet2
        mySortedSet2.Add(1);
        mySortedSet2.Add(2);
        mySortedSet2.Add(3);
        mySortedSet2.Add(4);
        mySortedSet2.Add(5);

        // Check if SortedSet and the specified
        // collection contain the same elements
        Console.WriteLine(mySortedSet1.SetEquals(mySortedSet2));
    }
}

Output:

True

Example 2:

// C# code to Check if SortedSet and
// the specified collection
// contain the same elements
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of strings
        SortedSet<string> mySortedSet1 = new SortedSet<string>();

        // adding elements in mySortedSet1
        mySortedSet1.Add("A");
        mySortedSet1.Add("B");
        mySortedSet1.Add("C");
        mySortedSet1.Add("D");
        mySortedSet1.Add("E");

        // Creating a SortedSet of strings
        SortedSet<string> mySortedSet2 = new SortedSet<string>();

        // adding elements in mySortedSet2
        mySortedSet2.Add("F");
        mySortedSet2.Add("G");
        mySortedSet2.Add("H");
        mySortedSet2.Add("I");
        mySortedSet2.Add("J");

        // Check if SortedSet and the specified
        // collection contain the same elements
        Console.WriteLine(mySortedSet1.SetEquals(mySortedSet2));
    }
}

Output:

False
