尝试序列化 int 时出错

Question

我正在尝试序列化我的整数，但出现以下错误：

InvalidCastException：无法从源类型转换为目标类型。

SaveLoad.Load()（在 Assets/SaveLoad.cs:24）指的是另一个 仅在唤醒时加载它的脚本loadgame.Awake()（在 Assets/loadgame.cs:8) 指的是

StatContainer.totalcoins = (int)bf.Deserialize(file);

我是数据序列化的新手，有人可以解释我的错误在哪里吗？

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<StatContainer> savedGames = new List<StatContainer>();

//it's static so we can call it from anywhere
public static void Save() {
    //SaveLoad.savedGames.Add(StatContainer.current);
    BinaryFormatter bf = new BinaryFormatter();
    //Application.persistentDataPath is a string, so if you wanted you can put that into debug.log if you want to know where save games are located
    FileStream file = File.Create (Application.persistentDataPath + "/savedGames.gd"); //you can call it anything you want
    bf.Serialize(file, StatContainer.current);
    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);
        StatContainer.totalcoins = (int)bf.Deserialize(file);
        file.Close();
        Debug.Log ("Loaded");
    }
}
}

调用Debug.Log(bf.Deserialize(file)); 看看它返回的是什么类型的对象，因为它显然不是一个int。
