C# | Check if the SortedSet contains a specific element

Last Updated : 01 Feb, 2019

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")); 
    } 
}
