问题
I know the #warning directive does not exist in vb.net... is there anything like it?
I want to be able to throw messages (warnings) at compiler time.
回答1:
As far as I've ever been able to find... no.
回答2:
It's not the same as preprocessor warning, but in the most cases where I need a warning for the user I generate one using the ObsoleteAttribute:
<ObsoleteAttribute("You should no used this method!", False)>
Sub MySub()
End Sub
However, since it is not the same as a preprocessor warning it will only trigger if someone uses the methode.
