How to convert DateTime? to DateTime

Question

I want to convert a nullable DateTime (DateTime?) to a DateTime, but I am getting an error:

Cannot implicitly convert type

Answer 1

Try this

DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate ?? DateTime.Now;

Answer 2

How about the following:

DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate.HasValue ? _objHotelPackageOrder.UpdatedDate.value : DateTime.Now;

Answer 3

MS already made a method for this, so you dont have to use the null coalescing operator. No difference in functionality, but it is easier for non-experts to get what is happening at a glance.

DateTime updatedTime = _objHotelPackageOrder.UpdatedDate.GetValueOrDefault(DateTime.Now);

Answer 4

You can also try Nullable(T) Properties:

DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate.HasValue 
    ? DateTime.Now : _objHotelPackageOrder.UpdatedDate.Value;

Answer 5

Here is a snippet I used within a Presenter filling a view with a Nullable Date/Time

memDateLogin = m.memDateLogin ?? DateTime.MinValue
