Question

나는 휴식 API (WCF 닷넷 4.0)이 있습니다

[ServiceContract] 
interface ISubscriptionService 
{ 
    [OperationContract] 
    [WebInvoke(Method = "GET", UriTemplate = Routing.ProductsRoute, BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)] 
    [Description("Получение информации о продуктах")] 
    ProductsResult Products(string timestamp, string transaction_id); 
} 

[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single, IncludeExceptionDetailInFaults = true)] 
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
class SubscriptionService : ISubscriptionService 
{ 
    public ProductsResult Products(string timestamp, string transaction_id) 
    { 
     SubscriptionProcessing processing = new SubscriptionProcessing(); 
     processing.SaveHistory(WebOperationContext.Current.IncomingRequest.UriTemplateMatch.RequestUri); 
     return processing.GetProducts(timestamp, transaction_id); 
    } 
} 

의 Web.config :

클래스 ProductsResult :

을

[DataContract(Name = "result", Namespace = "")] 
public class ProductsResult : CommonResult 
{ 
    public ProductsResult() 
    { 
     Products = new List<ProductResult>(); 
    } 

    [DataMember(Name = "products", Order = 3)] 
    public List<ProductResult> Products { get; set; } 
} 

클래스 일반 결과 :

[DataContract(Name = "result", Namespace = "")] 
public class CommonResult 
{ 
    public CommonResult() 
    { 
     TransactionId = string.Empty; 
     Error = new ErrorResult(); 
    } 

    [DataMember(Name = "transaction_id", Order = 1)] 
    public string TransactionId { get; set; } 
    [DataMember(Name = "error", Order = 2)] 
    public ErrorResult Error { get; set; } 
} 

클래스 ErrorResult :

[DataContract(Name = "error", Namespace = "")] 
public class ErrorResult 
{ 
    public ErrorResult() 
    { 
     Code = 0; 
     Message = string.Empty; 
    } 

    [DataMember(Name = "error", Order = 1)] 
    public int Code { get; set; } 
    [DataMember(Name = "message", Order = 2)] 
    public string Message { get; set; } 
}

이유는 무엇입니까?

위의 설명에서 ask125342는 클래스가 상속받은 클래스의 이름 데코레이터를 가질 수 없다고 말합니다. 이렇게하면 WCF 도움말 페이지의 자동 생성이 중단됩니다.
