How to create class variable name dynamically in C#

Question

class CarMaker
{
    public void MakeNewCar(int carCount)
    {
        string[] names = new string[carCount];
        Random random = new Random();            
        for (int i = 0; i < carCount; i++)
        {
            int randomNum = random.Next(0, 3);
            Car **howCanIDo** = new Car(null, (EModels)randomNum, (EColor)randomNum);
        }
    }
}

Please explain what are you trying to achieve by doing so? what is the logic you want? — Gilad Green, Dec 13 '19 at 08:50
why do you want to? What are you going to do with the cars? I suspect you want a list and you can add each to the list without each having a unique name — NDJ, Dec 13 '19 at 08:51

What you are trying to do is impossible, but you can achieve the same functionality with arrays, dictionaries... — Carlos López Marí, Dec 13 '19 at 08:59

By the collection names I assume you want to "hold" all the "names" (actually the references) to the Car objects you create in the loop. What you could do is instead have an array of type Car and add the items to it:

Car[] cars = new Car[carCount];
Random random = new Random();
for (int i = 0; i < carCount; i++)
{
    int randomNum = random.Next(0, 3);
    cars[i] = new Car(null, (EModels)randomNum, (EColor)randomNum);
}

And maybe even more convenient would be to just use lists:

List<Car> cars = new List<Car>();
for (int i = 0; i < carCount; i++)
{
    int randomNum = random.Next(0, 3);
    cars.Add(new Car(null, (EModels)randomNum, (EColor)randomNum));
}
