Remarks

If you attempt to set a database property to nullNothingnullptra null reference (Nothing in Visual Basic) using the .NET Framework, you will probably fail. This is because the .NET Framework uses the DBNull class instead of nullNothingnullptra null reference (Nothing in Visual Basic) for database values.
