Get the number of elements in the SortedSet in C#

To get the number of elements in the SortedSet, the code is as follows −

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");
      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);
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
AB
BC
CD
EF
Count of elements in SorteSet1 = 4 Elements in SortedSet2 (Enumerator for SortedSet)...
AB
BC
CD
DE
EF
HI
JK
Count of elements in SorteSet2 = 7

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);
      Console.WriteLine("Elements in SortedSet...");
      foreach (int res in set1){
         Console.WriteLine(res);
      }
      Console.WriteLine("Count of elements in SortedSet = " + set1.Count);
      set1.Clear();
      Console.WriteLine("Count of elements in SortedSet (updated) = " + set1.Count);
   }
}

Output

This will produce the following output −

Elements in SortedSet...
100
200
300
400
Count of elements in SortedSet = 4 Count of elements in SortedSet (updated) = 0
