Basic Operations

Helping function.

private static void Display(LinkedList<string> words, string test)
{
    Console.WriteLine(test);
    foreach (string word in words)
    {
        Console.Write(word + " ");
    }
}

Initialization of Linked List.

// in Main class
string[] words = { "the", "fox", "jumped", "over", "the", "dog" };
LinkedList<string> sentence = new LinkedList<string>(words);
Display(sentence, "The linked list values:");

//The linked list values:
//the fox jumped over the dog

Adding Operation.

sentence.AddFirst("today");
Display(sentence, "Test 1: Add 'today' to beginning of the list:");

//Test 1: Add 'today' to beginning of the list:
//today the fox jumped over the dog

Moving Operation.

LinkedListNode<string> mark1 = sentence.First;
sentence.RemoveFirst();
sentence.AddLast(mark1);
Display(sentence, "Test 2: Move first node to be last node:");

//Test 2: Move first node to be last node:
//the fox jumped over the dog today

Modifying Operation.

sentence.RemoveLast();
sentence.AddLast("yesterday");
Display(sentence, "Test 3: Change the last node to 'yesterday':");

//Test 3: Change the last node to 'yesterday':
//the fox jumped over the dog yesterday

mark1 = sentence.Last;
sentence.RemoveLast();
sentence.AddFirst(mark1);
Display(sentence, "Test 4: Move last node to be first node:");

//Test 4: Move last node to be first node:
//yesterday the fox jumped over the dog
