C# LinkedList

In C#, a linked list is a data structure that stores a collection of elements in a linear order. A linked list consists of nodes which hold data and a reference to the next node in the list. In this tutorial, we'll discuss how to use C# LinkedList class to create and manipulate linked lists.

Syntax

The syntax for creating a new LinkedList object in C# is as follows:

LinkedList<T> myList = new LinkedList<T>();

The type T represents the data type of the elements stored in the linked list. For example, to create a linked list of integers, we can use the following code:

LinkedList<int> myList = new LinkedList<int>();

Example

Let's say we want to create a linked list of strings. Here's how we can implement it:

LinkedList<string> myList = new LinkedList<string>();
myList.AddLast("Apple");
myList.AddLast("Banana");
myList.AddLast("Cherry");

foreach (string item in myList) {
   Console.WriteLine(item);
}

Output

When we run the example code above, the output will be:

Apple
Banana
Cherry

This is because we added three elements to the linked list and then printed them to the console using a foreach loop.

Explanation

In the example above, we created a new LinkedList object called "myList" that stores a collection of strings. We then added three elements to the linked list using the AddLast method. Finally, we printed the elements to the console using a foreach loop.

Use

Linked lists are useful when you need to store a collection of elements in a linear order and when you need to add or remove elements dynamically. Unlike arrays, linked lists can grow or shrink in size dynamically and don't require contiguous memory.

Important Points

  • Accessing an element in a linked list requires traversing the list from the beginning or end, which can be slow for large lists.
  • LinkedList class in C# provides a number of methods for adding, removing, and manipulating elements in the linked list.
  • LinkedListNode class is used to represent a node in the linked list and provides a method for accessing the next and previous node in the list.

Summary

In this tutorial, we discussed how to use C# LinkedList class to create and manipulate linked lists. We covered the syntax, example, output, explanation, use, and important points of using C# LinkedList class. With this knowledge, you can now use linked lists to store collections of elements in a linear order and add or remove elements dynamically.
