I have a class in VB.NET 2008.  I have date types that are not always assigned a value. Nulls from the database.  However, when I load the data into my class VB assigns a default date.  Is this default assignment avoidable?

You can try making the datatype a Nullable value
ie


Public Property SomeDate As Nullable(Of Date)
    Get
 
    End Get
    Set(ByVal value As Nullable(Of Date))
 
    End Set
End Property

Hi dbote;

Seeming you are using VS 2008 you can try making the Date data type a Nullable type as follows:

The following three statements are equivalent:

Dim dt? As DateTime
Dim dt As DateTime?
Dim dt As Nullable(Of DateTime)
