EF簡單的插入

Question

這是奇怪的事情...也許我有一個金髮碧眼的時刻或東西，但爲什麼不這項工作......

FLMCommsEntities dal = new FLMCommsEntities(); 
foreach (Email email in mail) 
{ 
    dal.EmailReceiveds.AddObject(new EmailReceived 
    { 
     FromAddress = email.From, 
     ToAddress = email.To, 
     EmailSubject = email.Subject, 
     EmailBodyHtml = email.BodyHtml, 
     EmailBodyPlain = email.BodyPlain, 
     ReceivedOn = (DateTime)email.Date, 
     AttachmentPath = email.AttachmentPath, 
     EmailSize = email.Size, 
     CreatedDate = DateTime.Now, 
     DownloadComplete = true, 
     ServerEmailID = email.ServerId 
    }); 
} 
// ask dal to save the new mail batch locally 
dal.SaveChanges(); 

它返回一個SQL異常是說我能」 t插入一個重複的主鍵值...顯然，我不是試圖插入主鍵值，而是做一個新的，而不是！

哎呀...

原來我是一個蠢蛋，忘了設置「身份Specifiction」關於在DB PK場這麼EF不知道它是自動填充了從生成的ID SQL Server。

沒關係......

了那裏到底:)
