Linq to SQl部分類不通過Web服務

Question

我使用linq to SQL作爲我的ORM，然後將linq to Sql對象跨Web服務傳遞到我的aspx UI頁面。

這一直工作正常，當我直接將Linq傳遞給sql對象時，他們得到序列化，我可以作爲json訪問他們。而且，當我傳遞poco DTO時，這個web服務也可以正常工作，因爲這些對象中的一些數據來自幾個不同的linq到SQL類。

我遇到的問題是當我嘗試使用linq到SQL類中定義的額外字段在自定義部分類中。部分類的自定義側的字段沒有通過Web服務，部分類的linq到sql生成側的字段確實碰到了。

當我創建對象時，字段就在那裏，我可以在visual studio調試器中看到它們，直到它們穿過服務，但它們不在另一端的json中。

下面是部分類

using System.Runtime.Serialization; 

namespace GPSO.ATOMWebDataLayer.LinqToSql 
{ 
    public partial class Geofence 
    { 
     public string FillColor { get; set; } 
    } 
} 

這裏是Web服務

using System; 
using System.Collections.Generic; 
using System.Configuration; 
using System.Data; 
using System.Data.SqlClient; 
using System.Diagnostics; 
using System.Linq; 
using System.Net; 
using System.ServiceModel; 
using System.ServiceModel.Activation; 
using System.ServiceModel.Web; 
using System.Text; 
using System.Web; 
using System.Web.Profile; 
using System.Web.Security; 
using System.Xml; 
using GPSO.ATOMWebBusinessLayer; 
using GPSO.ATOMWebDataLayer; 
using GPSO.ATOMWebDataLayer.LinqToSql; 
using GPSO.ATOMWebDataLayer.Objects; 
using GPSOnline.ReportWebService; 

using Contact = GPSO.ATOMWebDataLayer.LinqToSql.Contact; 
using Event = GPSO.ATOMWebBusinessLayer.Event; 
using Geofence = GPSO.ATOMWebBusinessLayer.Geofence; 

namespace GPSOnline 
{ 
    [ServiceContract(Namespace = "GPSOnline")] 
    [ServiceBehavior(IncludeExceptionDetailInFaults = true)] 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class ATOMWebService 
    { 
     private string _atomDbConnectionString; 
     private string _aspNetDbConnectionString; 
     private string _satelliteDbConnectionString; 

     [OperationContract] 
     [WebGet] 
     public IEnumerable<GPSO.ATOMWebDataLayer.LinqToSql.Geofence> GetAllGeofences() 
     { 
      NoCache(); 

      var geofenceRepo = new GeofenceRepository(GetConnectionString()); 
      return geofenceRepo.GetAllGeofences().ToList(); 
     } 
    } 
} 

and here is the Repository 

using System; 
using System.Collections.Generic; 
using System.Data; 
using System.Data.SqlClient; 
using System.Linq; 
using GPSO.ATOMWebBusinessLayer; 
using GPSO.ATOMWebDataLayer.LinqToSql; 
using GPSO.MapUtilities; 
using GPSO.Repository; 
using Microsoft.SqlServer.Types; 
using Geofence = GPSO.ATOMWebBusinessLayer.Geofence; 

namespace GPSO.ATOMWebDataLayer 
{ 
    public class GeofenceRepository 
    { 
     private static string _connectionString = ""; 

     public GeofenceRepository(string connectionString)   
     { 
      _connectionString = connectionString; 
     } 
     public IEnumerable<LinqToSql.Geofence> GetAllGeofences() 
     { 
      var dataContext = new AtomWebDataContext(_connectionString); 
      return allGeofences = dataContext.Geofences.ToList();  
     } 
} 

這裏是UI頁面

Answer 1

您需要使用[DataMemberAttribute]：

namespace GPSO.ATOMWebDataLayer.LinqToSql 
{ 
    [DataMember] 
    public partial class Geofence 
    { 
     public string FillColor { get; set; } 
    } 
}
