The INSERT statement conflicted with the FOREIGN KEY constraint "FK_JobList_aspnet_Membership". The conflict occurred in database "C:\JOBPOST\APP_DATA\ASPNETDB.MDF", table "dbo.aspnet_Membership", column 'UserId'.The statement has been terminated.INSERT語句衝突與外鍵約束的例外，但數據存儲
它總是拋出此異常，但數據已經成功地存儲在database.I多次與向度method.Right測試情況現在我在aspnet_membership中只有2個UserId，使用該uniqueidentifier UsrId列作爲FK_JobList_aspnet_Membership。主鍵表是aspnet_membership，外鍵表是我的JobList，它本身有索引JobId主鍵
我找不出我錯在哪裏。 2 UsrId只能從aspnet.mdf中，只添加1個joblist表，爲什麼它總是拋出異常，但成功存儲數據。
代碼：
JobPostDataContext db = new JobPostDataContext();
JobList newJob = new JobList();
MembershipUser curUser = Membership.GetUser(User.Identity.Name);
Guid user = new Guid(curUser.ProviderUserKey.ToString());
newJob.UserId =user;
newJob.JobTitle = ((TextBox)DetailsView1.FindControl("TB_JobTitle")).Text;
db.JobLists.InsertOnSubmit(newJob);
db.SubmitChanges();
