Question

for a project i’m currently working on, im trying to pass a set of objects all somehow linked to one object.

I’m currently blacked out and can’t seem to find a proper solution.

The situation is like this. I have a product object, on which a few insurance packages apply. I need to pass this information to the view, but I have to be able to retrieve the proper packages for the proper products. so it looks like this…

Product 1 has package 1, 2, 3
Product 2 has package 2,3,5,6
Product 3 has package 2,4,6,7

The problem is that there can be a different number of products and a different number of packages

Any ideas? The answer is probably simple, but I’m a little bit too tired to find it out…

Answer 1

How about this:

• Create a container class, as Simon suggested
• Inside the class, have these members:
  • List Products { get; set; }
  • List Packages { get; set; }
  • List GetPackages(Product product);

The GetPackages method can query the internal dictionary to determine which packages to return.

public class ProductsPackages
{
    private Dictionary<int, int> _map;

    public ProductsPackages(List<Product> products, List<Package> packages,
                            Dictionary<int, int> map)
    {
        _map = map;
    }

    public List<Product> Products { get; private set; }
    public List<Package> Packages { get; private set; }

    public List<Package> GetPackages(Product product)
    {
        return (from p in Packages
                join kvp in _map on p.ID == kvp.Value
                where kvp.Key == product.ID
                select p).ToList();
    }
}
