我建立一個mvc應用程序，首先使用EF代碼。我正準備開始。這裏是與我的問題有關的代碼。更新數據庫的第一次，得到錯誤

[Key]
public virtual int ID { get; set; }
public virtual int UserID { get; set; }
public virtual int Cycles { get; set; }
public virtual decimal Cost { get; set; }
public string Name { get; set; }
public virtual List<AdDisplayTime> DispalyTime { get; set; }
public virtual DateTime CreateDate { get; set; }
public virtual DateTime UpdateDate { get; set; }
public virtual int UpdatedBy { get; set; }
public virtual bool FullScreen { get; set; }
AdDisplayTimes型號
[Key]
public virtual int ID { get; set; }
public virtual int AdID { get; set; }
public virtual string DisplayTime { get; set; }
狀態模式
[Key]
public virtual int ID { get; set; }
public virtual string Name { get; set; }
這裏在我的移民類種子法
var adDisplayTimes = new List<AdDisplayTime>
{
new AdDisplayTime{AdID = 1,DisplayTime = "10:30"},
new AdDisplayTime{AdID = 1,DisplayTime = "10:40"},
new AdDisplayTime{AdID = 1,DisplayTime = "10:50"},
new AdDisplayTime{AdID = 1,DisplayTime = "11:00"}
};
context.Advertisements.AddOrUpdate(a => a.Name,
new Advertisement
{
Name = "Fisrt Ad",
OwnerID = 1,
Cycles = 125,
Cost = (decimal)234.45,
FileName = "test.jpg",
Tier = 1,
Path = "~/UploadedImages/Pending/test.jpg",
DispalyTime = adDisplayTimes,
CreateDate = DateTime.Now,
ValidFrom = DateTime.Now,
ValidTill = DateTime.Now.AddMonths(1),
FullScreen = true,
IsAdminAd = false,
Status = 1
}
);
context.AdDisplayTimes.AddOrUpdate(ad=>ad.AdID,
new AdDisplayTime { AdID = 1, DisplayTime = "10:30" },
new AdDisplayTime { AdID = 1, DisplayTime = "10:40" },
new AdDisplayTime { AdID = 1, DisplayTime = "10:50" },
new AdDisplayTime { AdID = 1, DisplayTime = "11:00" }
);
context.Statuses.AddOrUpdate(s=>s.Name,
new Status{Name = "Pending"},
new Status{Name = "Approved"},
new Status{Name = "Edited"},
new Status{Name = "Activated"},
new Status{Name = "DeActivated"}
);
當我運行從Visual Studio程序包管理器CONSOL命令「更新數據庫」我得到 這個
