C# 保存字节xna,保存某些数字时出现问题

C# 保存字节xna,保存某些数字时出现问题,c#,xna,isolatedstorage,C#,Xna,Isolatedstorage,我有点困惑,以下是我到目前为止所做的: public class SaveLoadSystem { String SAVEFILENAME = "gameSave2.sav"; Stats stats = new Stats(); GameProgressInformation gameInfo = new GameProgressInformation(); public SaveLoadSystem() { IsolatedSto

我有点困惑,以下是我到目前为止所做的:

public class SaveLoadSystem
{
    String SAVEFILENAME = "gameSave2.sav";
    Stats stats = new Stats();

    GameProgressInformation gameInfo = new GameProgressInformation();

    public SaveLoadSystem()
    {

        IsolatedStorageFile savegameStorage = IsolatedStorageFile.GetUserStoreForApplication();

        // open isolated storage, and write the savefile.
        if (savegameStorage.FileExists(SAVEFILENAME))
        {
            IsolatedStorageFileStream fs = null;
            try
            {
                fs = savegameStorage.OpenFile(SAVEFILENAME, System.IO.FileMode.Open);
            }
            catch (IsolatedStorageException e)
            {
            }

            if (fs != null)
            {

                byte[] saveBytes = new byte[256];
                int count = fs.Read(saveBytes, 0, 256);

                if (count > 0)
                {
                    for (int i = 0; i < stats.GetLevels; i++)
                    {
                        GameProgressInformation.LevelUnlockInfo levelInfo = new GameProgressInformation.LevelUnlockInfo();
                        // Think line below is wrong.
                        levelInfo.score = saveBytes[i * 4];
                        GameProgressInformation.levels.Add(levelInfo);

                    }
                    fs.Close();
                }

            }

        }
        else
        {
            for (int i = 0; i < stats.GetLevels; i++)
            {
                GameProgressInformation.LevelUnlockInfo levelInfo = new GameProgressInformation.LevelUnlockInfo();
                GameProgressInformation.levels.Add(levelInfo);
            }
        }
    }
    public void Save()
    {
        // Save the game.

        IsolatedStorageFile savegameStorage = IsolatedStorageFile.GetUserStoreForApplication();

        // open isolated storage, and write the savefile.
        IsolatedStorageFileStream fs = null;
        fs = savegameStorage.OpenFile(SAVEFILENAME, System.IO.FileMode.Create);

        if (fs != null)
        {
            for (int i = 0; i < GameProgressInformation.levels.Count; i++)
            {
                byte[] scoreBytes = System.BitConverter.GetBytes(GameProgressInformation.levels[i].score);
                fs.Write(scoreBytes, 0, scoreBytes.Length);

            }
            fs.Close();
        }



    }
}

我的困惑是如何在加载时获取所有必要的二进制数据,同时确保将正确的数据分配到正确的级别。我想这应该是一套4张的。感谢您的帮助

想出了怎么做。对流读取器的工作原理有错误的理解。

只需按照与编写数据完全相同的顺序读取数据即可。为什么要在保存二进制文件的方法中使用IsolatedStorageFileStream.Read?构造函数加载该文件,因此读取应该在那里。我遇到的问题是fs.read一次读取整个文件,而实际上我要么一次只想读取一个级别,要么我想要一种能够始终确保一次读取正确数量的数据的方式。对于未来的读者来说,详细说明错误可能会有所帮助。
