Check nullable types
C# provides a feature for object-relationship mapping. Since a date time field on the database can be empty but the DateTime type in C# can not be set to null, there is a solution called nullable types.
The syntax for is:
DateTime? date;
The problem is, the type of this object is not DateTime, so how it’s possible to check a nullable type?
It’s quite easy since all nullable types are of the type Nullable<>. To compare the previous variable date you can use following code:
date.GetType() == typeof(Nullable)
