Flex "Debug Only" Code?

Is there a way to mark certain parts of code so that they don't ev开发者_如何转开发en get compiled in release mode? I know you can do it in C# with syntax like this:

if #DEBUG
    trace("Debug");
else
    trace("Release");

Does Actionscript/Flex have any similar feature?

Yes, you can use:

CONFIG::debugging { 
    trace("Debug"); 
}
CONFIG::release { 
    trace("Release"); 
}

using the following compiler arguments:

-define+=CONFIG::debugging,true -define+=CONFIG::release,false
