Read Array Inside Array

Hi!

I'm trying to create an Array Called "Area" inside an Array called "Monsters" this will be used to load monsters depending the area. I have this working with 2 variables, (Area and AreaAlternative) so if you're in the area 01 any enemy that have area 01 in Area or AreaAlternative will appear (I have this function already done). But now I want to assign more than 2 possible areas for every enemy, that why i want to create the array to save all possibles areas for a enemy there.

Right now I have something like this:

 for (var i=0;i<AllEnemies.Length;i++){
         if(AllEnemies[i].frequency == Frequency.Second && (AllEnemies[i].areaLocated == PlayerScript.area || AllEnemies[i].areaLocatedAlternative == PlayerScript.area) && (AllEnemies[i].enviromentLocated == PlayerScript.enviroment || AllEnemies[i].enviromentLocatedAlternative == PlayerScript.enviroment) && (AllEnemies[i].attractedTo == PlayerScript.color || AllEnemies[i].attractedTo == "Any")){
         tempMonsters.Add(AllEnemies[i]);
         }

As you can see here I read the area of the monster to see if is the right one or not:

 (AllEnemies[i].areaLocated == PlayerScript.area || AllEnemies[i].areaLocatedAlternative == PlayerScript.area)

My problem is, if instead 2 variables I create an Array... How should I read it to see if the current area is between one of the possible Areas for that enemy? If there is another good option it would be great too!

Thank you!!
