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
