#warning directive in VB.net

Question

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.

Answer 1

就我所能找到的而言……不。

Answer 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.
