使用DataContract/Data成員爲WCF序列化對象

Question

我試圖序列化我的數據層對象。這些是具有屬性，方法和對象集合的複雜對象。

所有的類都從一個基類中繼承，它被序列化。

[DataContract] 
    [KnownType(typeof(Person))] 
    [KnownType(typeof(Client))] 
    [KnownType(typeof(Professional))] 
    [KnownType(typeof(ProfessionalApptHistory))] 
    [KnownType(typeof(DailySchedule))] 
    [KnownType(typeof(Option))] 
    [KnownType(typeof(PersonType))] 
    [KnownType(typeof(ProfessionClientInteractionType))] 
    [KnownType(typeof(ProfessionalClientInteractions))] 
    [KnownType(typeof(ProfessionalCalendar))] 
    public abstract class CMBase 
    { 
     protected designs3_OurTimeEntities _entities = new designs3_OurTimeEntities(); 
     [DataMember()] 
     public abstract bool IsPersisted { get; internal set; } 
    } 

我有一類人也得到系列化

[DataContract(Name = "Person")] 
    [KnownType(typeof(Professional))] 
    [KnownType(typeof(Client))] 
    public abstract class Person : CMBase 
    { 
     [DataMember()] 
     public int PersonId { get; internal set; } 
     [DataMember()] 
     public int PersonTypeId { get; set; } 
     [DataMember()] 
     public string Name { get; set; } 
     [DataMember()] 
     public string ContactNumber { get; set; } 
     [DataMember()] 
     public string ImageLocation { get; set; } 
     [DataMember()] 
     public Bitmap Image { get; internal set; } 
     [DataMember()] 
     public Guid MembershipUserId { get; internal set; } 
     [DataMember()] 
     public DateTime? ActivationStartDate { get; internal set; } 
     [DataMember()] 
     public string Email { get; internal set; } 
     [DataMember()] 
     public string Zip { get; set; } 
     [DataMember()] 
     public bool ShowDefaultPage { get; set; } 
     [DataMember()] 
     public bool IsClient { get; internal set; } 

     [DataMember()]   
     public override bool IsPersisted 
     { 
      get 
      { 
       if (this.PersonId == 0) 
       { 
        return false; 
       } 
       else 
       { 
        return true; 
       } 
      } 
      internal set 
      { 
       throw new NotImplementedException(); 
      } 
     } 

... }

然後我有這個類doenst得到系列化

[DataContract(Name = "Professional")] 
    public class Professional : Person 
    { 
     [DataMember()] 
     public DateTime DateStartedInProfession { get; set; } 
     [DataMember()] 
     public int? ShopId { get; set; } 
     [DataMember()] 
     public DateTime LastPayment { get; set; } 
     [DataMember()] 
     public DateTime NextPaymentDate { get; set; } 
     [DataMember()] 
     public DateTime TerminationDate { get; set; } 
     [DataMember()] 
     public int? Rating { get; internal set; } 
     [DataMember()] 
     public bool hasSystemAccess { get; internal set; } 
     [DataMember()] 
     public List<SaveResult> SaveResults { get; internal set; } 
... 
} 

我也有其他類沒有序列化，我不明白髮生了什麼。

Answer 1

看看Serialize a nullable int

它，你可以遵循一些方法。

Answer 2

變化

[DataMember()] 
public int? ShopId { get; set; } 

要

[DataMember()] 
public Nullable<int> ShopId { get; set; } 

我敢肯定，可空得到的序列化，我不是100％肯定這是你唯一的問題雖然。

Answer 3

晚到的遊客（就像我）： 繼承的問題，因爲它是在這裏討論： Definiting the Serialization DataMember in Interface and then using it in a class implementing said interface

如果Person將是一個界面，Profession將實現該接口，將工作。這是因爲屬性DataMember不能被繼承。
