在 Unity3d 中保存二进制文件时的序列化豁免

Question

I'm trying to save two elements, a string and a list of strings to a binary file. I have the class set outside the main script:

}
 the main script
}
[Serializable]
class SaveManager
{
    public string Info;
    public List<InfoSheetList> InfoSheetList ;

}

Then the function that calls it all

public void GetInfoSheet() 
    {

        DatabaseManager.Instance.SQLiteInit();
        string Info = PlayerPrefs.GetString ("Info");
        string date = PlayerPrefs.GetString ("Date");
        string Date=date.Replace("/","-");
        string Name = PlayerPrefs.GetString ("Name");
        string FilePath="C:/InfoSheets";

        DatabaseManager.Instance.SQLiteInit();
        InfoSheetList.Clear();
        InfoSheetList= DatabaseManager.Instance.MakeInfoSheetList();
        Debug.Log("How many in the list " + InfoSheetList.Count);

        BinaryFormatter bf = new BinaryFormatter();
        FileStream fs = File.Create(FilePath + "/" +Date+Name+"InfoSheet.gig");
        Debug.Log (fs);
        SaveManager sm= new SaveManager();
        sm.Info=Info;
        sm.InfoSheetList=InfoSheetList;
        //PlayerPrefs.DeleteAll ();

        bf.Serialize(fs, sm);
        fs.Close();
        Debug.Log(sm+ "Saved!");

Only I'm getting an exception- SerializationException: Type 'InfoSheet' in Assembly 'Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

What am I missing. The string is serializing, but the list is not. Thanks in advance!

Answer 1

Alexander, you are right. All I had to do is to add System.Serializable to the Infosheet Class. After I did that it worked! Thanks!
