C# | Intersection of SortedSet with a collection
SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.IntersectWith(IEnumerable<T>) method is used to modify the current SortedSet<T> object so that it contains only elements that are also in a specified collection.
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.IntersectWith(mySortedSet2);
Here, mySortedSet1 and mySortedSet2 are two SortedSet’s object.
Exception: This method will give ArgumentNullException if the SortedSet is null.
Below given are some examples to understand the implementation in a better way:
Example 1:
using System;
using System.Collections.Generic;
class GFG {
public static void Main()
{
SortedSet< int > mySortedSet1 = new SortedSet< int >();
mySortedSet1.Add(2);
mySortedSet1.Add(4);
mySortedSet1.Add(6);
mySortedSet1.Add(8);
mySortedSet1.Add(10);
SortedSet< int > mySortedSet2 = new SortedSet< int >();
mySortedSet2.Add(4);
mySortedSet2.Add(5);
mySortedSet2.Add(7);
mySortedSet2.Add(8);
mySortedSet2.Add(9);
Console.WriteLine( "The intersection of mySortedSet1 and mySortedSet2:" );
mySortedSet1.IntersectWith(mySortedSet2);
foreach ( int i in mySortedSet1)
{
Console.WriteLine(i);
}
}
}
|
Output:
The intersection of mySortedSet1 and mySortedSet2:
4
8
Example 2:
using System;
using System.Collections.Generic;
class GFG {
public static void Main()
{
SortedSet< string > mySortedSet1 = new SortedSet< string >();
mySortedSet1.Add( "Geeks" );
mySortedSet1.Add( "for" );
mySortedSet1.Add( "Geeks" );
mySortedSet1.Add( "Noida" );
mySortedSet1.Add( "Data Structures" );
SortedSet< string > mySortedSet2 = new SortedSet< string >();
mySortedSet2.Add( "Geeks" );
mySortedSet2.Add( "Java" );
mySortedSet2.Add( "Geeks Classes" );
mySortedSet2.Add( "C++" );
mySortedSet2.Add( "Noida" );
Console.WriteLine( "The Intersection of mySortedSet1 and mySortedSet2:" );
mySortedSet1.IntersectWith(mySortedSet2);
foreach ( string str in mySortedSet1)
{
Console.WriteLine(str);
}
}
}

Output:
The Intersection of mySortedSet1 and mySortedSet2 is:
Geeks
