The conversion of a datetime2 data type to a datetime data type Error

Question

I have a controller:

[HttpPost]
public ActionResult Create(Auction auction)
{
    var db = new EbuyDataContext();
    db.Auctions.Add(auction);
    db.SaveCh         


        

Answer 1

I had the same problem when I tried to save an unassigened DateTime member to the DB, while using EntityFramework. I read the answers here, and I learned that it can be solved by declaring the member as nullable. I tried it, and it worked! So here is a code snap, for those who need it:

public Nullable MyDateTime { get; set; }

or

public DateTime? MyDateTime { get; set; }

Later I could use it like bellow:

if(MyDateTime.HasValue)
{
    DoBlaBla(MyDateTime.Value);
}

or just assign a value to it like nothing had happen...

MyDateTime = DateTime.Now;
