From msdn I get this:
#pragma warning disable warning-list #pragma warning restore warning-list In the examples, both disable and restore are used. Is it necessary to restore if I want it disabled for a whole file?
Like, if I do not restore, how far does it carry? Are the warnings disabled for everything compiled after that? Or just for the rest of that file? Or is it ignored?
If you do not restore the disabling is active for the remainder of the file.
Interestingly this behaviour is not defined in the language specification. (see section 9.5.8) However the 9.5.1 section on Conditional compilation symbols does indicate this ‘until end of file behaviour’
Given the ‘pre-processor’ is actually part of the lexical analysis phase of compilation it is likely that this behaviour is an effective contract for Microsoft’s and all other implementations for the foreseeable future (especially since the alternate would be hugely complex and non deterministic based on source file compilation order)
