How to create a SortedSet in C#?

To create a 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);       }       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);       }    } }

Output

This will produce the following output −

Elements in SortedSet1... AB BC CD EF Elements in SortedSet2 (Enumerator for SortedSet)... AB BC CD DE EF HI JK

Example

Let us now see another example −

 Live Demo

using System; using System.Collections.Generic; public class Demo {    private static bool demo(int i){       return ((i % 10) == 0);    }    public static void Main(String[] args){       SortedSet<int> set1 = new SortedSet<int>();       set1.Add(200);       set1.Add(215);       set1.Add(310);       set1.Add(500);       set1.Add(600);       Console.WriteLine("SortedSet elements...");       foreach (int i in set1){          Console.WriteLine(i);       }       Console.WriteLine(" ");       set1.RemoveWhere(demo);       Console.WriteLine("SortedSet after removing some elements...");       foreach (int i in set1){          Console.WriteLine(i);       }    } }

Output

This will produce the following output −

SortedSet elements... 200 215 310 500 600 SortedSet after removing some elements... 215
