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

This should work:

if (!string.IsNullOrWhiteSpace(dateTimeEnd))
    eventCustom.DateTimeEnd = DateTime.Parse(dateTimeEnd);
else
    eventCustom.DateTimeEnd = null;

Note that this will throw an exception if the string is not in the correct format.
