Union of SortedSet to a collection in C#

To compute the Union of SortedSet to a Collection, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      SortedSet<int> set1 = new SortedSet<int>();
      set1.Add(50);
      set1.Add(100);
      set1.Add(150);
      Console.WriteLine("SortedSet1 elements...");
      foreach(int ele in set1) {
         Console.WriteLine(ele);
      }
      SortedSet<int> set2 = new SortedSet<int>();
      set2.Add(100);
      set2.Add(150);
      set2.Add(200);
      set2.Add(250);
      Console.WriteLine("SortedSet2 elements...");
      foreach(int ele in set2) {
         Console.WriteLine(ele);
      }
      Console.WriteLine("Union...");
      set1.UnionWith(set2);
      foreach(int ele in set1) {
         Console.WriteLine(ele);
      }
   }
}

Output

This will produce the following output −

SortedSet1 elements...
50
100
150
SortedSet2 elements...
100
150
200
250
Union...
50
100
150
200
250

Example

Let us see another 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);
      set1.Add(400);
      set1.Add(500);
      set1.Add(600);
      Console.WriteLine("SortedSet1 elements...");
      foreach(int ele in set1) {
         Console.WriteLine(ele);
      }
      SortedSet<int> set2 = new SortedSet<int>();
      set2.Add(100);
      set2.Add(200);
      set2.Add(300);
      set2.Add(400);
      set2.Add(500);
      set2.Add(600);
      Console.WriteLine("SortedSet2 elements...");
      foreach(int ele in set2) {
         Console.WriteLine(ele);
      }
      Console.WriteLine("Union...");
      set1.UnionWith(set2);
      foreach(int ele in set1) {
         Console.WriteLine(ele);
      }
   }
}

Output

This will produce the following output −

SortedSet1 elements...
100
200
300
400
500
600
SortedSet2 elements...
100
200
300
400
500
600
Union...
100
200
300
400
500
600
