How to set DateTime to null

Question

Using C#. I have a string dateTimeEnd.

If the string is in right format, I wish to generate a DateTime and assign it to eventCustom.DateTimeEnd

Answer 1

Now, I can't use DateTime?, I am using DBNull.Value for all data types. It works great.

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
  ? DBNull.Value
  : DateTime.Parse(dateTimeEnd);
