List of List C# question or something else any pointers in coding this

Question

I need some help in coding this in C#

I have a list of Baskets and their Global_Weights in overall Basket in Kilograms:

Basket1, Basket2, Basket3, Basket4

0.1, 0.3, 0.9,0.6

Each of the Basket consist of the following thing:

Name,Level1, level2,Local_Weights

Name: String type

Level1:Double Type

Level2:Double Type

Local_Weights:Double Type

Each Basket will consist of N number of (Name,Level1, level2,Local_Weights) and there are M Baskets N and M are variable which will be user Input

Should I be using List of list for this or something else any pointer on how to go about coding this?

How will I be accessing the members inside each of the Basket and perform calculation on them.

What is the larger problem? Depending on what you are doing there are multiple ways to correctly create the list/other structures. For instance if you are doing a sorting algorithm it my be better to use arrays for immediate access. — Joshua

You would use a class Basket that contains a list of objects of the class BasketInfo and create a list of that Basket class:

class Basket
{
    public Basket()
    {
        BasketInfos = new List<BasketInfo>();
    }

    public double GlobalWeight
    {
        get
        {
            return BasketInfos.Sum(x => x.LocalWeight); 
        }
    }

    public IList<BasketInfo> BasketInfos { get; set; }
}

class BasketInfo
{
    public string Name { get; set; }
    public double Level1 { get; set; }
    public double Level2 { get; set; }
    public double LocalWeight { get; set; }
}

var baskets = new List<Basket>();

Something like this perhaps?

class Basket
{
    private List<Payload> _payload = new List<Payload>();

    public List<Payload> Payload
    {
        get { return _payload; }
    }

    public double Weight
    { 
        get { /* calculate total weight */; }
    }
}

class Payload
{
    public string Name { get; set; }
    public double Level1 { get; set; }
    public double Level2 { get; set; }
    public double Local_Weight { get; set; }
}

And perhaps some usage, like this:

var baskets = new List<Basket>();

// Create a new basket with some payload
var newBasket = new Basket();
newBasket.Payload.Add(   
    new Payload {Name = "MyName", Level1 = 1, Level2 = 2, Local_Weight = 3});
baskets.Add(newBasket);

// Access all payloads in all baskets for example
foreach (var payload in baskets.SelectMany(basket => basket.Payload))
{
    Console.WriteLine(payload.Name);
}

Perhaps a book like Head First C# could also be of use. Good luck!

You could use something of this sort.

Dictionary<string, List<MyClass>> var = new Dictionary<string, List<MyClass>>();//where string key is the basket name, MyClass is a class containing properties like Name,Level1, level2,Local_Weights
