得到此错误:

System.Data.SqlClient.SqlException:将datetime2数据类型转换为日期时间数据类型会导致超出范围的值.

我的实体对象全部排列到DB对象.

我通过Google发现只有一个引用此错误:

谷歌的结果

阅读本文之后,我记得我们确实添加了2个字段,然后从VS 2010更新了实体模型.我不确定他的意思是"手工编码"差异.我没有看到任何.

我在代码中所做的就是填充实体对象,然后保存.(我还在代码中填充新字段)我用DateTime.Now... 填充了日期字段

代码的重要部分是: ctx.SaveChanges(SaveOptions.AcceptAllChangesAfterSave);

该数据库是SQL Server 2008.

思考？

其余的错误:

我有实体框架的问题.特别是我不能做插入或更新操作.错误信息:
