SortedSet Class in C#
The SortedSet class in C# represents a collection of objects that is maintained in sorted order.
Following are the properties of the SortedSet class −
| Sr.No | Property & Description |
|---|---|
| 1 |
Comparer Gets the IComparer<T> object that is used to order the values in the SortedSet<T>. |
| 2 |
Count Gets the number of elements in the SortedSet<T>. |
| 3 |
Max Gets the maximum value in the SortedSet<T>, as defined by the comparer. |
| 4 |
Min Gets the minimum value in the SortedSet<T>, as defined by the comparer. |
Following are some of the methods of the SortedSet class −
| Sr.No | Method & Description |
|---|---|
| 1 |
Add(T) Adds an element to the set and returns a value that indicates if it was successfully added. |
| 2 |
Clear() Removes all elements from the set. |
| 3 |
Contains(T) Determines whether the set contains a specific element. |
| 4 |
CopyTo(T[]) Copies the complete SortedSet<T> to a compatible onedimensional array, starting at the beginning of the target array. |
| 5 |
CopyTo(T[], Int32) Copies the complete SortedSet<T> to a compatible onedimensional array, starting at the specified array index. |
| 6 |
CopyTo(T[], Int32, Int32) Copies a specified number of elements from SortedSet<T> to a compatible one-dimensional array, starting at the specified array index. |
| 7 |
CreateSetComparer() Returns an IEqualityComparer object that can be used to create a collection that contains individual sets. |
Example
Let us now see some examples −
To check if the SortedSet contains a specific element, the code is as follows −
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);
}
Console.WriteLine("Does the SortedSet1 contains the element DE? = "+set1.Contains("DE"));
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("SortedSet2 is a superset of SortedSet1? = "+set2.IsSupersetOf(set1));
}
}
Output
This will produce the following output −
Elements in SortedSet1... CD Does the SortedSet1 contains the element DE? = False Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet2 is a superset of SortedSet1? = True
To get an enumerator that iterates through the SortedSet, the code is as follows −
Example
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
