I have field DateTime? Date

I need check Date for null and set min value.

var anyDate = Date ?? DateTime.MinValue();

or

var anyDate = Date.HasValue ? Date.Value : DateTime.MinValue();

what is right ?

Answer 1

Both are. First one is shorter and then has my preference. Check : Which is preferred: Nullable<>.HasValue or Nullable<> != null?

Answer 2

I think you can use this

var anyDate = Date.GetValueOrDefault(DateTime.MinValue);

Since you want to check for null and in that case assign a default value, this roughly translates to the form

if(Date.HasValue)
   return Date.Value;
return defaultvalue;
