Loading data from BinaryFormater

Unity Engine
1

Hello

I have a few problems figuring out how to load the data back after saving using Binary Formater, here is my code:

using System.Collections.Generic;

using UnityEngine;
using System.Collections;
//You must include these namespaces
//to use BinaryFormatter
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
 
public class SaveSystem : MonoBehaviour {
	[System.Serializable]
    public class SaveEntry{
		public int _CurHealth;
		public int _MaxHealth;
	    public int _CurExp;
	    public int _MaxExp;
        public int _Damage;
		public int _PhiDefense;
		public int _MagDefense;
		public int _Gold;
		public float _PlayerPositionX;
		public float _PlayerPositionY;
		public float _PlayerPositionZ;
		public string _Level;
	}

    //High score table
 SaveEntry SaveData = new SaveEntry();
   public void Save(string SaveSlot){
	GameObject _Player = GameObject.FindGameObjectWithTag("Player");
    playerHealth _Healthscript = _Player.GetComponent<playerHealth>();
	attack _AttackScript = _Player.GetComponent<attack>();
		SaveData._CurHealth = _Healthscript.CurHealth;
		SaveData._MaxHealth = _Healthscript.MaxHealth;
	    SaveData._CurExp = _Healthscript.CurExp;
	    SaveData._MaxExp = _Healthscript.MaxExp;
        SaveData._Damage = _AttackScript.PlayerDamage;
		SaveData._PhiDefense = _Healthscript.PhisicalDefense;
		SaveData._MagDefense = _Healthscript.MagicalDefense;
		SaveData._Gold = _Healthscript.Gold;
		SaveData._PlayerPositionX = _Player.transform.position.x;
		SaveData._PlayerPositionY = _Player.transform.position.y;
		SaveData._PlayerPositionZ = _Player.transform.position.z;
		SaveData._Level = Application.loadedLevelName;
        //Get a binary formatter
        var b = new BinaryFormatter();
        //Create an in memory stream
        var m = new MemoryStream();
        //Save the scores
        b.Serialize(m, SaveData);
        //Add it to player prefs
        PlayerPrefs.SetString(SaveSlot, Convert.ToBase64String(m.GetBuffer()));
		PlayerPrefs.Save();
		Debug.Log ("Save complete " + SaveSlot);
    }
 
   public void Load(string SaveSlot){
	GameObject _Player = GameObject.FindGameObjectWithTag("Player");
    playerHealth _Healthscript = _Player.GetComponent<playerHealth>();
	attack _AttackScript = _Player.GetComponent<attack>();
        //Get the data
        var data = PlayerPrefs.GetString(SaveSlot);
        //If not blank then load it
        if(!string.IsNullOrEmpty(data))
        {
            //Binary formatter for loading back
            var b = new BinaryFormatter();
            //Create a memory stream with the data
            var m = new MemoryStream(Convert.FromBase64String(data));
        SaveData = b.Deserialize(m);
		_Healthscript.CurHealth = SaveData._CurHealth;
		_Healthscript.MaxHealth = SaveData._MaxHealth;
	   	_Healthscript.CurExp = SaveData._CurExp;
	   	_Healthscript.MaxExp = SaveData._MaxExp;
      	_AttackScript.PlayerDamage =  SaveData._Damage;
	  	_Healthscript.PhisicalDefense =  SaveData._PhiDefense;
	  	_Healthscript.MagicalDefense =  SaveData._MagDefense;
	  	_Healthscript.Gold =  SaveData._Gold;
	  	_Player.transform.position = new Vector3 (SaveData._PlayerPositionX,SaveData._PlayerPositionY,SaveData._PlayerPositionZ);
		//Application.LoadLevel(SaveData._Level);
        }
    }
 
}

My problem is I dont know how to properly save the data back into the SaveData variable after loading the playerpref and converting it with the BinaryFormater, another problem I have is I dont know how to load the level the player was in when he saved because If do application.loadlevel() all the data I just loaded obviously gets erased.

Ok I figured it out I needed to use SaveEntry SaveData = (SaveEntry)b.Deserialize(m); and now it works but my other question remains, how can I load the level, every time I do that the data I just loaded gets erased.
