Question

If I had a CarsDataStore representing a table something like:

Cars
--------------
Ford | Fiesta
Ford | Escort
Ford | Orion
Fiat | Uno
Fiat | Panda

Then I could do

IEnumerable<Cars> fords = CarsDataStore["Ford"];

Is this a bad idea? It’s inconsistent with the other datastore objects in my api (which all have a single column PK indexer), and I’m guessing most people don’t expect an indexer to return a collection in this situation.

Answer 1

I wouldn’t expect an indexer to return a collection but then the compiler would tell me that if I ran into any problems.

However I would personally implement something more along the lines of

IEnumerable<Cars> fords = CarsDataStore.GetCarsByType("Ford");
