Question

I know in VBA how to do a Select..Case comparison for a controls Type, as such:

Select Case TypeName(ctrl)
  case is = "ListBox"
    ...
  case is = "ComboBox"
    ...
  ...
End Select

In VB.Net, can i use the general value, as above, or will i have to have a Namespace qualifier in the text?

Currently implementation:

public function Validate(byref ctrl as WebControl) as boolean
  select case TypeName(ctrl)
    case is = "TextBox"
      ....
    case is = "Label"
      ....
    ...
  End select
End Function

You don’t need the “name” of the type, you can use the type directly:

    Select Case True
        Case TypeOf c Is TextBox
            ' its a Textbox
        Case TypeOf c Is Label
            ' its a label
        Case Else
            'foo
    End Select
