Nullable Data Extension Methods

[ForumAccount]

John, was there a reason that you didn't use a generic method? Such as:

Public Function GetNullable(Of T As Structure)(ByVal source As Common.DbDataReader, _
                                               ByVal name As String) As T?
    Dim ordinal As Integer = source.GetOrdinal(name)
 
    Return If(source.IsDBNull(ordinal), _
              New T?(), _
              DirectCast(source.GetValue(ordinal), T?))
 
End Function
