Question

我是ASP.NET MVC的新手，我想从我的一个类的属性创建一个自定义数据类型。我知道这是可能的，但不幸的是，我缺乏知道我的代码有什么问题的知识。

我收到以下错误消息：

"Schema specified is not valid. Errors: 
The relationship 'GarethLewisWeb.Models.Photo_Set' was not loaded because the type
'GarethLewisWeb.Models.Photo' is not available.
The following information may be useful in resolving the previous error:
The property 'Orientation' on the type 'GarethLewisWeb.Models.Photo' has a property 
type of 'GarethLewisWeb.Models.Photo+Orientations' which cannot be mapped to a
PrimitiveType."

以下是我认为导致问题的Photo.cs类的代码。

public class Photo
{
    public int PhotoID { get; set; }
    public int PhotoOrder { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public string FileLocation { get; set; }
    public Orientations Orientation { get; set; }
    public int Height { get; set; }
    public int Width { get; set; }
    public int Rating { get; set; }
    public bool FeaturedPhoto { get; set; }

    public enum Orientations
    {
        Square = 0,
        Landscape = 1,
        Portrait = 2
    }

    public virtual Set Set { get; set; }
    public virtual PhotoExif PhotoExif { get; set; }
}

任何帮助指定！感谢。
