help with a list of strings

[Violet_82]

Hi guys,
I'm looking into MVC and I'm reasing this tutorial http://www.asp.net/mvc/overview/older-versions/hands-on-labs/aspnet-mvc-4-fundamentals
I've got to the point of adding a model and the class they add is this:

public class StoreIndexViewModel
{
  public int NumberOfGenres { get; set; }
  public List<string> Genres { get; set; }
}

I'm not really familiar with this syntax public List<string> Genres and I was wondering if anybody can help me understanding this a bit better. They refer to it as a list of string, so why not use an array of strings? Is that also what they call a "generic"? How do I get values in that list of string and how do I get them out please?
thanks

You can probably google about 'php list vs array' and get what you want and maybe you will be more understand after go throught examples in this link: http://php.net/manual/en/function.list.php

Sorry, please do ignore my post. Thought it is in php section.

Hi

This is indeed a Generic List.

You can create a List of anything eg List<Customer> or List<Invoice>

To Add things you just use:

var model = new StoreIndexViewModel();

model.Genres.Add("Horror");
model.Genres.Add("Romance");
model.Genres.Add("Drama");

You can pull them all out with things like:

foreach (var genre in mode.Genres)
{
    //Do something with genre here
}

Why is this better than an array? Many reasons. Check out this video:
