使用隔离存储在WP7中保存集合

Question

我正在构建一个具有多个锦标赛的应用程序，每个锦标赛都具有多个集合。

IsolatedStorage只有在我写锦标赛名称时才能正常工作，如果我尝试在其集合中添加任何内容，它就会崩溃。

我的比赛班

public class TournamentMain
{
    public int ID = 0;
    public string name { get; set; }
    public double buy_in { get; set; }
    public double re_buy { get; set; }
    public double add_on { get; set; }
    public int blindindex = 1;
    public int placeindex = 1;
    public int playerindex = 1;
    public ObservableCollection<Blind> blinds { get; set; }
    public ObservableCollection<Player> players { get; set; }
    public ObservableCollection<Place> places { get; set; }
    public ObservableCollection<Paidplace> paidplaces {get; set;} 

    public TournamentMain() {
        players = new ObservableCollection<Player>();
        places = new ObservableCollection<Place>();
        blinds = new ObservableCollection<Blind>();
        paidplaces = new ObservableCollection<Paidplace>();

   } }

我的存储类

public class StorageSaveing
{
    static XmlSerializer serializer;
    public static void saveIT()
    {


        using (var store = IsolatedStorageFile.GetUserStoreForApplication())

            using (var stream = new IsolatedStorageFileStream("data.txt",
                                                    FileMode.Create,
                                                       FileAccess.Write,
                                                       store))
            {

                serializer = new XmlSerializer(typeof(ObservableCollection<TournamentMain>));
                serializer.Serialize(stream, App.tournaments);
            }

    }


    public static ObservableCollection<TournamentMain> loadIT()
    {
     using(   var store = IsolatedStorageFile.GetUserStoreForApplication())
     using (var stream = new IsolatedStorageFileStream("data.txt",
                                            FileMode.OpenOrCreate,
                                               FileAccess.Read,
                                               store))

       using(  var reader = new StreamReader(stream))
       {
         serializer = new XmlSerializer(typeof(ObservableCollection<TournamentMain>));
         return reader.EndOfStream
                ? new ObservableCollection<TournamentMain>()
          : (ObservableCollection<TournamentMain>)serializer.Deserialize(reader);
        }
    }
}

应用关闭并打开时会被调出

任何帮助是极大的赞赏！！：）

所有序列化都需要作为显式的getter和setter

public class TournamentMain
{
    public int ID { get; set; }
    public string name { get; set; }
    public double buy_in { get; set; }
    public double re_buy { get; set; }
    public double add_on { get; set; }
    public int blindindex { get; set; }
    public int placeindex { get; set; }
    public int playerindex { get; set; }
    public ObservableCollection<Blind> blinds { get; set; }
    public ObservableCollection<Player> players { get; set; }
    public ObservableCollection<Place> places { get; set; }
    public ObservableCollection<Paidplace> paidplaces {get; set;} 

    public TournamentMain() 
    {
        ID = 0;
        blindindex = 1;
        placeindex = 1;
        playerindex = 1;
        players = new ObservableCollection<Player>();
        places = new ObservableCollection<Place>();
        blinds = new ObservableCollection<Blind>();
        paidplaces = new ObservableCollection<Paidplace>();
   } 

}

还要确保对象Player，Place，Blind和Paidplace具有明确的getter和setter
