C#/.NET - get random element from set

HashSet random element example

using System;
using System.Collections.Generic;
using System.Linq;

namespace Test
{
	class Program
	{
		public static void Main(string[] args)
		{
			Random random = new Random();

			HashSet<string> set = new HashSet<string>()
			{
				"A", "B", "C", "D", "E", "F"
			};

			for (int i = 0; i < 10; ++i)
			{
				int index = random.Next(set.Count);
				string entry = set.ElementAt(index);

				Console.WriteLine(entry);
			}
		}
	}
}

Output:

A
F
C
B
A
E
C
D
A

Note: in above example Enuberable.ElementAt Linq method has been used to get element.
