C# Lists 📃 

using System; using System.Collections.Generic; namespace MyFirstProgram { class Program { static void Main(string[] args) { // List = data structure that represents a list of objects that can be accessed by index. // Similar to array, but can dynamically increase/decrease in size // using System.Collections.Generic; List food = new List(); food.Add("pizza"); food.Add("hamburger"); food.Add("hotdog"); food.Add("fries"); //Console.WriteLine(food[0]); //Console.WriteLine(food[1]); //Console.WriteLine(food[2]); //Console.WriteLine(food[3]); //food.Remove("fries"); //food.Insert(0, "sushi"); //Console.WriteLine(food.Count); //Console.WriteLine(food.IndexOf("pizza")); //Console.WriteLine(food.LastIndexOf("fries")); //Console.WriteLine(food.Contains("pizza")); //food.Sort(); //food.Reverse(); //food.Clear(); //String[] foodArray = food.ToArray(); foreach (String item in food) { Console.WriteLine(item); } Console.ReadKey(); } } }

Summarize : List is an advanced version of array with many useful methods but it consumes more memory than array . Method of list Declare a list List strList = new List(); // style 1 List strList = new(); // style 2 (quicker) Add/Insert/Remove an element Add an element strList.Add("a"); Insert an element strList.Insert(1, "b"); // 1 = index Remove an element strList.Remove("a"); Size of a list strList.Count() Index of a specific element First index strList.IndexOf("a"); Last index strList.LastIndexOf("a"); Check whether a list contains a specific element strList.Contains("a"); Sort the list Sort the list alphabetically strList.Sort(); Sort the list anti-alphabetically strList.Reverse(); Clear the list strList.Clear(); Switch between array and list Convert from array to list List strList = strArray.ToList(); // style 1 List strList = new(); strList.AddRange(strArray); // style 2 Convert from list to array String[] strArray = strList.ToArray(); If you want to print list for testing . static void Print(List strList) { foreach (String str in strList) { Console.Write(str); } Console.WriteLine(); } static void Print(List intList) // method overloading { foreach (int i in intList) { Console.Write(i); } Console.WriteLine(); }

I'm 90% sure I tried in the past to learn and understand Arrays and failed hard, even with friends trying to explain, and even tho this is a tutorial for lists, thank you for teaching me what I wanted to do with Arrays in less than a minute xD

How do I get the average value? I want to use the Variable.Average(); Command and then assign this average to another variable to display.

Thanks! Everything very good explained

Nice tutorial Thanks

Dude you're a life saver im not joking.

amazing video, great teaching man

Thanks Bro!

can we add custom Lists like arrays with for loop like List.Add([ i ])=Console.ReadLine(); Can we do something like that for Lists? or are they only added manually for Website application

On behalf of Lists everywhere, I take exception, sir, to your characterization of Lists as "wasting" more memory. It is true that Lists use more memory than arrays; but we'll have you know that those memory resources are very well spent!

I was trying to move from js to C# ,array in C# was feeling so uncomfortable for me. This video made me clear how do i create array as js in C#.

youre so good at explaining things oh my god

Thanks for the video Bro.

This list method can be used to make a todo list, right?

what about dynamic arrays?

Thanks to your efforts :D

Descriptive ,simple , concentrate and short video

A random comment down below.

Is there any benefit to this over doing something like: string[] food = new string[] { "pizza", "hamburger", "hotdog", "fries"}; and then using '(0, food.Length);', which seems to circumvent the need to declare a definite array size?

Super random comment 9999

W channel. Tq very much sir!

You're the goat Mr Bro !

How do you change number 3 to 0 in list? example: list numbers = new list {1,2,3,4,5,6,7,8,9}; Number 3 needs to be number 0. Is there any way to do some list.Replace() method or anything? Thank you.
