What is the purpose of ElementAt?

 Posted by Niladri.Biswas on 6/9/2013 | Category: LINQ Interview questions | Views: 1726 | Points: 40

The ElementAt operator retrieves the element at a given index in the collection.

string[] names =

{ "Niladri", "Arina", "Bob","Foo", "Bar" };
Random random = new Random(DateTime.Now.Millisecond);

string name = names.ElementAt(3);

Console.WriteLine("The name chosen is '{0}'.", name);

This code produces the following sample output:

The name chosen at random is 'Foo'.
