WCF DataContract與DataContract接口

Question

WCF的新功能。

DataContact類可以從Interface繼承嗎？

如：

[DataContract(Namespace = ...........)] 
public class VesselSequence : IVesselSequence 
{ 

    [DataMember] 
    public int AllocationId { get; set; } 

    [DataMember] 
    public string ScenarioName { get; set; } 
} 

interface VesselSequence : IVesselSequence 
{ 
    public int AllocationId { get; set; } 
    public string ScenarioName { get; set; } 
} 

Answer 1

肯定是可以的，但要記住，如果你正在返回你必須定義KnownTypes的反序列化引擎屬性的接口類型，因此它可能在另一端反序列化發送接口。

Answer 2

你可以這樣做：

[DataContract(Namespace = ...........)] 
public class VesselSequence : IVesselSequence 
{ 
    [DataMember] 
    public int AllocationId { get; set; } 
    [DataMember] 
    public string ScenarioName { get; set; } 
} 

interface IVesselSequence 
{ 
    int AllocationId { get; set; } 
    string ScenarioName { get; set; } 
} 

你不能做到這一點，黯然道：

public class VesselSequence : IVesselSequence 
{ 
    public int AllocationId { get; set; } 
    public string ScenarioName { get; set; } 
} 

[DataContract(Namespace = ...........)] 
interface IVesselSequence 
{ 
    [DataMember] 
    int AllocationId { get; set; } 
    [DataMember] 
    string ScenarioName { get; set; } 
}
