[SOLVED] "IOException: Sharing violation on path" Trying to save multiple files

Question

What I'm trying to do is save 2 separate files as ".dat" file in different locations so that my code is more manageable.

My current serializable file has 2000+ lines of code, and that gets tedious to sift through, so I'm trying to create a second serializable file to split the saves, instead of adding another 1500 line to one file.

Script #1: GameControl (This one works)

public class GameControl : MonoBehaviour {

 using UnityEngine;
 using System.Collections;
 using System;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.IO;
 
 void OnEnable () {
         Load();
 }
 
 void Start () {
 InvokeRepeating("Save", 1.0f, 0.25f);
 }
 
 public void Save () {
         BinaryFormatter bf = new BinaryFormatter();
         FileStream file = File.Create(Application.persistentDataPath + "/playerInfo.dat");
         PlayerData data = new PlayerData();
 
     //hundreds of values
     bf.Serialize(file, data);
     file.Close();
 }
 
 public void Load () {
         if(File.Exists(Application.persistentDataPath + "/playerInfo.dat")) {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Open(Application.persistentDataPath + "/playerInfo.dat", FileMode.Open);
             PlayerData data = (PlayerData)bf.Deserialize(file);
             file.Close();

     //hundreds of values
 }

Script #1: MissionHanlder(This one messes everything up)

 using UnityEngine;
 using System.Collections;
 using System;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.IO;
 
 public class MissionHandler : MonoBehaviour {
 
 void OnEnable () {
         Load();
     }

 void Start () {
     InvokeRepeating("Save", 1.3f, 0.23f);
 }
 
 public void Save () {
         BinaryFormatter bf = new BinaryFormatter();
         DirectoryInfo dirInf = new DirectoryInfo(Application.persistentDataPath + "/sm_save");
         if(!dirInf.Exists){dirInf.Create();}
         FileStream file = File.Create(Application.persistentDataPath + "/sm_save/sm_ParameterData.dat");
 
     //a few dozen values
 }
 
 public void Load () {
         if(File.Exists(Application.persistentDataPath + "/sm_save/sm_ParameterData.dat")) {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Open(Application.persistentDataPath + "/sm_save/sm_ParameterData.dat", FileMode.Open);
             MissionData data = (MissionData)bf.Deserialize(file);
             file.Close();
 
     //a few dozen values
 }
 
 }

To Clarify, these are running concurrent with each other

Turns out, this code segment is VERY important.

 bf.Serialize(file, data);
 file.Close();

For future references: I had this problem happen to me and none of these solutions I found online fixed it. Turns out the solution was to close Microsoft Excel which I was using to visualize the .csv file I was modify with the game.

I hope this helps.

What I did was declare my filestream on class level then gave the filestream different values in my methods, as in using it to read from a file in one and write to a file in another. Structure I used:

  Class myClass
 {    
         FileStream stream1;
 
         void MethodToWrite()    
        {
              stream1 = new FileStream(path, FileMode.Create);
              using(var file = new StreamWriter(stream))
              {
                      file.WriteLine("What I want to write");
              }
        }
 
      void MethodToRead()
      {
             stream1 = new FileStream(path, FileMode.Open);
             var file = new StreamReader(stream1);
             string value = file.ReadLine();
      }

 }

This is not the most elegant way to solve this problem but it works.

New just add delay of 1 or 2 sec before saving this happend because you just create that file and trying to write the data .

SaveToDisk(Application.persistentDataPath + "/" + fileName + ".json", json);

public static IEnumerator SaveToDisk(string path,string data)

{

yield return new WaitForSeconds(1); File.WriteAllText(path, data);

}
