C# !Conditional attribute?
First, having the Conditional
attribute is not equivalent to having #if
inside the method. Consider:
ShowDebugString(MethodThatTakesAges());
With the real behaviour of ConditionalAttribute
, MethodThatTakesAges
doesn't get called - the entire call including argument evaluation is removed from the compiler.
Of course the other point is that it depends on the compile-time preprocessor symbols at the compile time of the caller, not of the method :)
But no, I don't believe there's anything which does what you want here. I've just checked the C# spec section which deals with conditional methods and conditional attribute classes, and there's nothing in there suggesting there's any such mechanism.
Nope.
Instead, you can write
#if !ShowDebugString
[Conditional("FALSE")]
#endif
Note that unlike [Conditional]
, this will be determined by the presence of the symbol in your assembly, not in your caller's assembly.
