Trying to list names from text files in dropdown options.,Trying to list info from txt files.

I wanted to add a custom gear maker to my game. This uses text files to list attributes of the gear. I can create the files however when I try and pull from the mods directory in streaming assets to retrieve the gear name from within the text files I get the error "object reference not set to an instance of an object" for line 29. I want to add the names of the objects to a dropdown menu. My code is below. using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using System.IO;

 public class armouryChooser : MonoBehaviour
 {
     DirectoryInfo dir = new DirectoryInfo(Application.streamingAssetsPath + "/Mods/");
     FileInfo[] info;
     string[] generalMods = new string[100];
     List<string> ArmouryMods, WeaponMods, EnemyMods;
 
     public Dropdown weapon, armour;
 
     // Start is called before the first frame update
     private void Start()
     {
         print("Running Start");
         int i = 0;
         info = dir.GetFiles();
         foreach (FileInfo f in info)
         {
             generalMods[i] = File.ReadAllText(info[i].ToString());
             string[] temp = generalMods[i].Split(',');
             switch (int.Parse(temp[0]))
             {
                 case 0:
                     WeaponMods.Add(File.ReadAllText(info[i].ToString()));
                     break;
 
                 case 1:
                     ArmouryMods.Add(File.ReadAllText(info[i].ToString()));
                     break;
 
                 case 2:
                     EnemyMods.Add(File.ReadAllText(info[i].ToString()));
                     break;
             }
 
             i++;
             print(WeaponMods[0]);
         }
 
         int w = 0;
         foreach(string f in WeaponMods)
         {
             string[] temp = WeaponMods[w].Split(',');
             weapon.options.Add (new Dropdown.OptionData() { text = (temp[w]) });
         }
 
         int a = 0;
         foreach (string f in ArmouryMods)
         {
             string[] temp = ArmouryMods[a].Split(',');
             armour.options.Add(new Dropdown.OptionData() { text = (temp[a]) });
         }
 
         armour.value = 1;
         armour.value = 0;
 
         weapon.value = 1;
         weapon.value = 0;
     }
 }
