How to sort HashSet<t> object

However a HashSet collection is not sorted and cannot contain duplicate elements. At that time when you need to collection in sorted order then you can use the List<t> class together with the Sort method or if you are on .net framework 4 then you can use the SortedSet<t> class. But in this article i will show you that we can use the array class to sort the hashset object, see the following example:
 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create hashset object of the int type
            HashSet<int> objHash = new HashSet<int>();
            // add items to hashset object
            objHash.Add(14);
            objHash.Add(12);
            objHash.Add(11);
            objHash.Add(13);
 
            // Print all elements of the hashset object
            Console.WriteLine("before sort");
            foreach (int i in objHash)
            {
                Console.WriteLine(i);
            }
 
            //Declare a new Array object of int type
            int[] arrInt;
            // bind items to array from hashset object
            arrInt = objHash.ToArray();
            // Sort the array
            Array.Sort(arrInt);
            // Clear hashset object
            objHash.Clear();
            //Merge the array into hashset object with sort order
            objHash.UnionWith(arrInt);
            //Print the all items of the hashset object
            Console.WriteLine("After sort");
            foreach (int i in objHash)
            {
                Console.WriteLine(i);
            }
 
        }
    }
}

 
The above program will produce the following output:
 
before sort
14
12
11
13
after sort
11
12
13
14
