C # Array or Collection

Question

How would you approach this? I have a list of data that has two things that should be stored in price and position, is there anyway to store this in an array, not knowing the total number of rows that I will have? Or should I use a collection if they can be multidimensional?

thank

Answer 1

Yes - I would recommend you look at the general list. Using this, you can simulate your data and store as many elements as possible.

for instance

  public class PricedItem
    {
        public decimal Price { get; set; }
        public object Item { get; set; }
    }

They can then be saved / retrieved to List<PricedItem> - or as a "list of rated items".

Hope that helps

Answer 4

you may have

struct Item
{
    float Price;
    string ItemName;
}

and

List<Item> items = new List<Item>();
items.Add(new Item{Name="item1", Price=19.99});
