Code tip: Nullable datetime in C#

Nullable types are used when you need to represent the value of an underlying type. By default DateTime is not nullable in C# because it is a Value type, but using the Nullable construct (or the ? shorthand), you can assign the null literal to the DateTime type. Syntax is below:

 DateTime? dt = null;  
 Nullable<DateTime> dt = null;
