I had used AddDays(x) method before on DateTime objects and it was working fine but now my object is defined like this:
public DateTime? To_Date { get; set; }
And looks like this one does not have a AddDays method. How can I call it then?
Because DateTime? can be in a state representing null, you need to consider what to do if it's null.
The most obvious thing to do is to stay with a value of null (the day after null is null).
DateTime? later = ToDate.HasValue
? To_Date.Value.AddDays(numberOfDays)
: (DateTime?)null;
It maybe that there's some meaningful default date you can use, in which case:
DateTime later = (ToDate ?? defaultDate).AddDays(numberOfDays);
This will use defaultDate when ToDate has no value, and the value of ToDate otherwise.
