考虑使用DataContractResolver序列化错误
本文关键字:序列化 错误 DataContractResolver | 更新日期: 2023-09-27 18:06:35
我的桌面wpf应用程序与mvc 4 web api通信。我正在尝试读取所有数据库条目。这是一个简单的接口:
public interface IEventRepository
{
IEnumerable<Event> GetAll();
}
这是存储库:
public class EventRepository : IEventRepository
{
private List<Event> events = new List<Event>();
public EventRepository()
{
HeronEntities context = new HeronEntities();
events = context.Events.ToList();
}
public IEnumerable<Event> GetAll()
{
return events;
}
}
这是控制器:
public class EventController : ApiController
{
static readonly IEventRepository repository = new EventRepository();
public IEnumerable<Event> GetAllEvents()
{
return repository.GetAll();
}
}
事件类看起来像这样:
public partial class Event
{
public Event()
{
this.Comments = new HashSet<Comment>();
this.Rates = new HashSet<Rate>();
this.RawDates = new HashSet<RawDate>();
}
public int ID { get; set; }
public string Title { get; set; }
public string Summary { get; set; }
public string SiteURL { get; set; }
public string ContactEmail { get; set; }
public string LogoURL { get; set; }
public int EventType_ID { get; set; }
public Nullable<int> Location_ID { get; set; }
public Nullable<System.DateTime> BegginingDate { get; set; }
public string nTrain { get; set; }
public string Content { get; set; }
public virtual ICollection<Comment> Comments { get; set; }
public virtual Conference Conference { get; set; }
public virtual ICollection<Rate> Rates { get; set; }
public virtual ICollection<RawDate> RawDates { get; set; }
public virtual EventType EventType { get; set; }
public virtual Location Location { get; set; }
}
当我尝试访问控制器时,我得到上面提到的failed to serialize the response body for content type
的错误。Event
类序列化存在一些问题。我对包含基本类型的类使用了完全相同的代码,并且工作得很好。克服这种序列化问题的最佳方法是什么?
我已经禁用了延迟加载和代理类生成。这就解决了问题。
public EventRepository()
{
HeronEntities context = new HeronEntities();
context.Configuration.LazyLoadingEnabled = false;
context.Configuration.ProxyCreationEnabled = false;
events = context.Events.ToList();
}
