C# | Check if the SortedSet contains a specific element

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.Contains(T) Method is used to check if a SortedSet contains a specific element or not.

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 virtual bool Contains (T item);

Here, T is Type Parameter, i.e, the type of elements in the set.

Return Value: The method returns True if the set contains the specified item, otherwise, returns False.

Example 1:

// C# code to check if the SortedSet
// contains a specific element
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of integers
        SortedSet<int> mySortedSet = new SortedSet<int>();

        // adding elements in mySortedSet
        mySortedSet.Add(2);
        mySortedSet.Add(4);
        mySortedSet.Add(6);
        mySortedSet.Add(8);
        mySortedSet.Add(10);

        // Checking if the SortedSet contains
        // a specific element
        Console.WriteLine(mySortedSet.Contains(6));
    }
}

Output:

True

Example 2:

// C# code to check if the SortedSet
// contains a specific element
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of strings
        SortedSet<string> mySortedSet = new SortedSet<string>();

        // adding elements in mySortedSet
        mySortedSet.Add("Mumbai");
        mySortedSet.Add("Bangalore");
        mySortedSet.Add("Chandigarh");
        mySortedSet.Add("Noida");
        mySortedSet.Add("Jaipur");
        mySortedSet.Add("Kolkata");

        // Checking if the SortedSet contains
        // a specific element
        Console.WriteLine(mySortedSet.Contains("Delhi"));
    }
}

Output:

False
