Saving and loading array (/list) of integers locally

Hi,

Currently I've spend many hours on trying to figure somet$$anonymous$$ng out that should be very simple to do. I'm trying to save and load multiple arrays, or lists, of integers locally. T$$anonymous$$s tutorial: http://gamedevelopment.tutsplus.com/tutorials/how-to-save-and-load-your-players-progress-in-unity--cms-20934 helped me a lot, but for whatever reason I can't seem to implement it with arrays.

T$$anonymous$$s is what I've currently made of it, but obviously it doesn't work: using UnityEngine; using System.Collections; using System.Collections.Generic; using System.Runtime.Serialization.Formatters.Binary; using System.IO;

 public static class SaveLoad {
  
     public static List<int> list1 = new List<int>();
     public static List<int> list2 = new List<int>();
     //I want to have 50 lists (or arrays)   
           
     public static void Save(List<int> myList1, List<int> myList2) {
         SaveLoad.list1.Add(myList1);
         SaveLoad.list2.Add(myList2);
         BinaryFormatter bf = new BinaryFormatter();
         FileStream file = File.Create (Application.persistentDataPath + "/savedGames.gd"); 
         bf.Serialize(file, SaveLoad.list1);
         bf.Serialize(file, SaveLoad.list2);
         file.Close();
     }   
      
     public static void Load() {
         if(File.Exists(Application.persistentDataPath + "/savedGames.gd")) {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Open(Application.persistentDataPath + "/savedGames.gd", FileMode.Open);
             SaveLoad.list1 = (List<int>)bf.Deserialize(file);
             SaveLoad.list2 = (List<int>)bf.Deserialize(file);
             file.Close();
         }
     }
 }

Once that's working I would also like to know the proper way of using t$$anonymous$$s through another C# script, but first t$$anonymous$$ngs first :) .

Thanks in advance for your input!
