A dictionary object that uses ranges of values for keys

Question

I have need of a sort of specialized dictionary. My use case is this: The user wants to specify ranges of values (the range could be a single point as well) and assign a v

Answer 1

I would make a little Interval class, which would something like that:

public class Interval
{
    public int Start {get; set;}
    public int End {get; set;}
    public int Step {get; set;}
    public double Value {get; set;}

    public WriteToDictionary(Dictionary dict)
    {
        for(int i = Start; i < End; i += Step)
        {
            dict.Add(i, Value);
        }
    }
}

So you still can a normal lookup within your dictionary. Maybe you should also perform some checks before calling Add() or implement some kind of rollback if any value is already within the dictionary.
