Question

I’ve got a mysql table that has entries with a unique ID, then 3 properties.

I’m displaying the IDs in a ListBox, and the other information goes on other parts of my page. It gets re-used often enough that I don’t want to do another query every time I need to reference it. My question is this: What kind of data structure should I use to hold the row data?

Is a 2-dimensional array the best option? If so, is it poor style to use a Hashtable with the key being the ID and the value being a reference to an array containing all the values for that row?

I’m using .NET 4, and coding this in C#.

Answer 1

A model looks appropriate to represent a row:

public class Foo
{
    public string Id { get; set; }
    public string Prop1 { get; set; }
    public string Prop2 { get; set; }
    public string Prop3 { get; set; }
}

and IEnumerable<Foo> to represent your SQL table. You would then of course have a repository with methods allowing you to fetch a single model given it’s Id or other criteria and to fetch all models. Then bind this model to your GUI.
