C# Creating a primary enum list that has dependant enum sublists

Question

Primary List:

enum CarMake
{
   Ford, Toyota, Honda
}

Secondary List:

enum CarModel
{
  Explorer, // Ford
  Corolla, // Toyota
  Camry, // Toyota
  Civic, // Honda
  Pilot //  Honda

}

Is there some means of linking the 2 enum lists together?

So that when using CarMake the program will know which CarModels are linked?

No, as you want to achieve is not possible, but it would be possible using Dictionaries and string for CarModel

var dict = new Dictionary<CarMake,string[]>();

dict.Add(CarMake.Ford, new string[] { "Explorer" });
dict.Add(CarMake.Toyota, new string[] { "Corolla","Camry" });
dict.Add(CarMake.Honda, new string[] { "Civic","Pilot" });

then if you want to retrieve the cars from Honda, you call it as shown below:

var hondaCars = dict[CarMake.Honda]

If you, instead, want to retrieve the car-maker from the model you just call:

var carMaker = dict.FirstOrDefault(key => key.Value.Contains("Civic")).Key

You could even make it a `Dictionary>`. – juharr Mar 09 '16 at 17:48
@juharr thanks, I have added the possibility of retrieving either the cars from the manufacturer, or the manufacturer from the car. – Michael Mairegger Mar 09 '16 at 17:54

You might wanna look into this.

Combine multiple enums into master enum list

allCars.AddRange(Enum.GetValues(typeof(CarModel)).Cast<Enum>());
allCars.AddRange(Enum.GetValues(typeof(CarMake)).Cast<Enum>());

Since if you make the list carModel into a master list in theory you get your answer
