My problem is solved , the Exception occur because acadimicEndDate property is usually return this invalid value '1/1/0001 12:00:00 AM' when replace this value by this value '1/3/2018 12:00:00 AM' my Exception has disappeared

The error message you posted here doesn't help much. Is the Id field marked as Key?
