我阅读了几篇与 InsertOnSubmit is not working 相关的帖子，但没有一个能解决我的问题。下面是我的代码，我在我的 BackupPlan 表中手动插入了一条记录，当我运行 linq 时，从数据库中选择记录，我尝试在下面插入的 2 条新记录返回并显示在日志中，但是当我签入服务器资源管理器时 - > 数据连接 -> 表 BackupPlan 只有手动插入的记录在那里，而不是新记录。我还尝试更新现有记录并删除，但没有成功，也没有任何异常。此外，我添加了一个列 Id 并将其设置为我的 BackupPlan 表的主键，检查了 db.GetChangeSet() 并返回 2 个插入语句处于挂起状态，但 db.SubmitChanges() 运行后没有成功。知道我在这里缺少什么吗？？？:(
