Storing a variable name within a variable using asp.net c#

Question

Is it possible to reference a variable/array using another variable in asp.net c#? EG.

alfaromeo = new string[] {"lots of stuff"};
astonmartin = new string[] {"lots of stuff"};
audi = new string[] {"lots of stuff"};
bentley = new string[] {"lots of stuff"};
bmw = new string[] {"lots of stuff"};

etc

string targetArray = "audi";

for(int i=0; i<targetArray.Length; i++){
    // do stuff with tha array
}

There is a reason the arrays are all called different names and I'm not using a multi dimensional array to referance them.

Can this be done, or do I need to use some sort of look up array to reference them?

Thanks in advance.

string targetArray = "audi"; is this a String or a String[] ? — Marco

A string. This would be where a just store the name of the array I want to use, unless you are seeing something a lot more logical than I. Which is very possible :) — Strontium_99

No, not local variables.

I'd rather put the stuff in a dictionary:

var dict = new Dictionary<string, string[]>
{
  { "alfaromeo", new string[] {"lots of stuff"} }
  // etc...
}

Or if you insist on variables, put them into fields of a class, and use reflection:

class Z {
  public static string[] alfaromeo = new string[] {"lots of stuff"};
}
// ...
typeof(Z).GetField("alfaromeo", BindingFlags.Static | BindingFlags.Public).GetValue(null);

Sorry to be so dim, but if I use a dictionary, how do I reference them once stored?

dict["alfaeomeo"] The string becomes the key into the dictionary. Try here for some better help
