Generic linked list class without using System.Collections libraries C#

A linked list is a collection of controls which maintain a reference or pointer to the next and previous items in the list. A circular linked list is the same with the exception that the first item in the list contains a reference to the last and vice versa.
In order to create a linked list without using the Collection libraries you just need to create a class that contains an array of your objects. Each object should hold a reference to the next and previous items in the list. Your parent class that contains the array needs to manage these references via methods like Add, Remove, Insert, etc...
