setting datetime to null

I have two DateTime variables first period and second period and with each period i have a date range between two date for each period. My issue is that i usually set my dates to null withn i load the page but for these dates i cannot set them to null which i would like rather than setting a specific date. 

DateTime firstPeriodBeginDate = DateTime.Today.AddMonths(-3);
DateTime secondPeriodBeginDate = DateTime.Today.AddMonths(-2);

I would like it set to null so that it will equal to the values selected from the date picker by the user when used to render results.

The DateTime structure cant be null.

But you can use a nullable DateTime

DateTime? dateTime;
dateTime = null;

and check for null

if (dateTime.HasValue)

More information: C# Nullable DateTime

hope this helps

DateTime is a non-nullable value type, so cannot be null.

You can use a Nullable<DateTime> for such a thing:

DateTime? firstPeriodBeginDate = DateTime.Today.AddMonths(-3);
DateTime? secondPeriodBeginDate = null;
