Check if a SortedSet is a subset of the specified collection in C#

To check if a SortedSet is a subset of the specified collection, 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...");       foreach (string res in set2){          Console.WriteLine(res);       }       Console.WriteLine("SortedSet1 is a subset of SortedSet2? = "+set1.IsSubsetOf(set2));    } }

Output

This will produce the following output −

Elements in SortedSet1... AB BC CD EF Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet1 is a subset of SortedSet2? = True

Example

Let us 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("CD");       set1.Add("CD");       set1.Add("CD");       set1.Add("CD");       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...");       foreach (string res in set2){          Console.WriteLine(res);       }       Console.WriteLine("SortedSet1 is a subset of SortedSet2? = "+set1.IsSubsetOf(set2));    } }

Output

This will produce the following output −

Elements in SortedSet1... CD Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet1 is a subset of SortedSet2? = True
