C# | Check if SortedSet and a specified collection share common elements

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet.Overlaps(IEnumerable) Method is used to check whether a SortedSet and a specified collection share common elements or not.

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.Overlaps(mySortedSet2);

Here, mySortedSet1 and mySortedSet2 are two SortedSet.

Return Value: The function returns True if mySortedSet1 and mySortedSet2 share atleast one common element, else returns False.

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

Example 1:

// C# code to Check if SortedSet 
// and a specified collection 
// share common 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(5); 

        mySortedSet1.Add(6); 

        mySortedSet1.Add(7); 

        mySortedSet1.Add(8); 

        mySortedSet1.Add(9); 

        // Creating a SortedSet of integers 

        SortedSet<int> mySortedSet2 = new SortedSet<int>(); 

        // adding elements in mySortedSet2 

        mySortedSet2.Add(7); 

        mySortedSet2.Add(8); 

        mySortedSet2.Add(9); 

        mySortedSet2.Add(10); 

        mySortedSet2.Add(11); 

        // Check if SortedSet and a specified 

        // collection share common elements 

        Console.WriteLine(mySortedSet1.Overlaps(mySortedSet2)); 

    } 
}

Output:

True

Example 2:

// C# code to Check if SortedSet 
// and a specified collection 
// share common 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 a specified 

        // collection share common elements 

        Console.WriteLine(mySortedSet1.Overlaps(mySortedSet2)); 

    }
