Assigning null value to DateTime

[Bill Gower]

How do I assign a null value to a datetime variable?

DateTime DateNonMember = DateTime.Parse("").ToString();

This doesn't work.

I also tried

DateTime DateNonMember = DBNull.Value

How do I assign a null value to a datetime variable?

You can't. DateTime is a value type, like int, char and boolean.
(That's not an exhaustive list!)

If you're using .NET 2.0, you can use DateTime? which is a nullable
version of DateTime. See
http://pobox.com/~skeet/csharp/csharp2/nullable.html for more
information.

DateTime is a value type so you can't assign null to it.
You can assign null to Nullable<DateTime> (DateTime? in c#)
