"Name" array after a string c# [duplicate]

I've started an old project again (with new ideas and in Unity) and I'm stuck. Basically I need a lot of public arrays (mostly so they appear in the editor). Is there a way to "name" those arrays using existing strings? For example :

string[] arrayNames = new string[]{"FirstArray", "SecondArray", "ThirdArray"};
for (int i=0; i<arrowNames.Length; i++){
    //Here i would create the new array using the string
    public Sprite[] arrowNames[i] = new Sprite[10];
    //Code to populate new array comes here
}

This code is just the idea of what i need. Anyone know a way to do this? Thanks.
