I am using:
If MyObject.Equals(DBNull.Value) Then
....
Do you think this work?
At least I didn't have any problem in my code.
Thanks,
Miguel

In ASP.NEt 1.1 or in 2.0 without a nullable type, you would use DbNull.Value

In 2.0, you have nullable types. I assume you are not using them however, or
are using VB.NET. In VB.NET 2.0, you use
Dim nullable1 As Nullable(Of DateTime) = New Nullable(Of DateTime)
If Not nullable1.HasValue Then
End If

Hello,
Inside a class I have 4 propertiy types:
1. String
2. Boolean
3. Mail.MailPriority
4. Mail.MailAddressCollection
I need to check if each property is null, i.e., if it wasn't defined
any value for them.
How can I do it?
I tried NULL but it got an error to use System.DBNull but I got error
again.
Thanks,
Miguel
