C# | Remove a specified item from SortedSet

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.Remove(T) Method is used to remove a specified item from the SortedSet.

Properties:

  • In C#, SortedSet class can be used to store, remove or view elements.
  • It maintains ascending order and does not store duplicate elements.
  • It is suggested to use SortedSet class if you have to store unique elements and maintain ascending order.

Syntax:

public bool Remove (T item);

Here, item is the specified item which is to be removed from the SortedSet.

Note: If the SortedSet<T> object does not contain the specified element, the object remains unchanged and no exception is thrown.

        mySortedSet.Add(10);
  
        // Removing element "4" if found
        mySortedSet.Remove(4);
  
        // Displaying the elements in mySortedSet
        foreach(int i in mySortedSet)
        {
            Console.WriteLine(i);
        }
  
        Console.WriteLine("After Using Method");
  
        // Removing element "14" if found
        mySortedSet.Remove(14);
  
        // Displaying the element in mySortedSet
        foreach(int i in mySortedSet)
        {
            Console.WriteLine(i);
        }
