Why can't I save an array?

After following a Brackey's tutorial I've created a save and load system for my software, however, while testing it I've found it is only successfully saving a single integer, for some reason it's not saving my array. This is a pretty big problem since I need to also save lists and even dictionaries. Please help me figure out what's going on.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System;
 
 public class GameManager : MonoBehaviour
 {
     // Variables
     // Misc Variables 
     public int ValueInt;
     public string[] ValueStringArray = { };
 
 
 
 
     // Misc Controllers
     public void ReadIntInput(string number)
     {
         // Sets Single Number Value
         ValueInt = Convert.ToInt32(number);
 
         Debug.Log("int saved");
     }
 
     public void ReadStringInput(string temporary)
     {
         // Adds Values To Temp Arrays
         List<string> ValueStringList = new List<string>(ValueStringArray);
         ValueStringList.Add(temporary);
         ValueStringArray = ValueStringList.ToArray();
 
         Debug.Log("string saved");
     }
 
 
 
 
 
     // Save System
     public void SaveState()
     {
         SaveSystemNew.SaveUserData(this);
 
         Debug.Log("Saved " + ValueInt);
 
         foreach (string i in ValueStringArray)
         {
             Debug.Log("Saved " + i);
         }
     }
 
 
 
 
 
     // Load Systems
     public void LoadState()
     {
         SaveDataNew data = SaveSystemNew.LoadUserSave();
 
         ValueInt = data.ValueInt;
 
         Debug.Log("Loaded " + ValueInt);
 
         foreach (string i in ValueStringArray)
         {
             Debug.Log("Loaded " + i);
         }
     }
 }
