使用隔離存儲在WP7中保存集合

Question

我正在構建一個包含多個比賽的應用程序，並且每個比賽都有多個集合。

只有我寫錦標賽名稱時，如果我嘗試向它的集合添加任何內容，它纔會崩潰，IsolatedStorage才能正常工作。

我的比賽類

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>(); 

    } } 

我的存儲類

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); 
     } 
    } 
} 

它叫出來的時候應用程序關閉和打開

任何幫助，非常感謝!! :)

Answer 1

一切序列化需要顯式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>(); 
    } 

}

還要確保對象播放機，廣場，失明，Paidplace有explicite getter和setter
