Question

I am looping thorugh a datatable and and printing each row to the console and I keep on getting a dbnull error. I inserted an if statement in my loop to try and catch it, but I can’t seem to get it to work. Any ideas?

Thanks!

                Do While reader.Read
                For i As Integer = 0 To reader.FieldCount - 1

                    If reader.IsDBNull(i) Then
                        Console.Write(Nothing)
                    Else
                        Console.Write(reader.GetString(i))
                    End If

                Next
                Console.WriteLine(Environment.NewLine())

Changing Console.Write(Nothing) to Console.Write(“Nothing”) might remove one error, and reader.GetString(i) might throw InvalidCastException errors – you should catch this. reader.IsDBNull(i), however, looks correct.
