What can cause SqlDateTime overflow when using LINQ to SQL SubmitChanges ()?

Question

In my code, I have several objects that are added to the repository, I tried to run the Save () repository function once at the end of all loops, and also naming it after each object that is added. But anyway, I still get SqlDateTime overflow when db.SubmitChanges () in .save () repository ... any idea?

 SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Answer 1

Basically the problem is that the Sql DATETIME data type starts on 1/1/1753, while DateTime.MinValue is 1/1/0000 (or something like that). So, if you do not initialize the date properties, you get Sql overflows.

Parameters for correction:

a) DateTime -.

b) sql, DATETIME2, .NET DateTime. [ SQL 2008]

Answer 2

OnValidate() SqlDateTime.MinValue SqlDateTime.MaxValue.
