Intersection of SortedSet with a collection in C#

To get the intersection of SortedSet with a Collection, the code is as follow −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedSet<int> set1 = new SortedSet<int>();
      set1.Add(100);
      set1.Add(200);
      set1.Add(300);
      SortedSet<int> set2 = new SortedSet<int>();
      set2.Add(450);
      set2.Add(200);
      set2.Add(650);
      set2.Add(300);
      set2.Add(800);
      Console.WriteLine("Does it contain the same elements? = "+set1.SetEquals(set2));
      set1.IntersectWith(set2);
      Console.WriteLine("Resultant SortedSet...");
      foreach(int val in set1){
         Console.WriteLine(val);
      }
   }
}

Output

This will produce the following output −

Does it contain the same elements? = False
Resultant SortedSet...
200
300

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedSet<string> set1 = new SortedSet<string>();
      set1.Add("AB");
      set1.Add("BC");
      set1.Add("CD");
      set1.Add("EF");
      set1.Add("PQ");
      set1.Add("ST");
      Console.WriteLine("Elements in SortedSet1...");
      foreach (string res in set1){
         Console.WriteLine(res);
      }
      Console.WriteLine("Count of elements in SorteSet1 = "+set1.Count);
      SortedSet<string> set2 = new SortedSet<string>();
      set2.Add("BC");
      set2.Add("CD");
      set2.Add("DE");
      set2.Add("EF");
      set2.Add("AB");
      set2.Add("HI");
      set2.Add("JK");
      Console.WriteLine("Elements in SortedSet2 (Enumerator for SortedSet)...");
      SortedSet<string>.Enumerator demoEnum = set2.GetEnumerator();
      while (demoEnum.MoveNext()) {
         string res = demoEnum.Current;
         Console.WriteLine(res);
      }
      Console.WriteLine("Count of elements in SorteSet2 = "+set2.Count);
      set1.IntersectWith(set2);
      Console.WriteLine("Resultant SortedSet...");
      foreach(string val in set1){
         Console.WriteLine(val);
      }
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
AB
BC
CD
EF
PQ
ST
Count of elements in SorteSet1 = 6
Elements in SortedSet2 (Enumerator for SortedSet)...
AB
BC
CD
DE
EF
HI
JK
Count of elements in SorteSet2 = 7 Resultant SortedSet...
AB
BC
CD
EF
