Visual C++ 10 中的 __FILE__ 预处理器宏扩展为源模块的名称，但使用小写，例如

The __FILE__ preprocessor macro in Visual C++ 10 expands to the name of the source module, but in lowercase, e.g.

c:\path\to\my\file\somesource.cpp

当文件名实际上是

SomeSource.cpp

是否可以改变这种行为?

Is it possible to change this behaviour?

推荐答案

根据 Hans Passant 的建议，我 询问Microsoft Connect 并得到以下答案:

As suggested by Hans Passant, I asked the question on Microsoft Connect and got the following answer:

感谢您注意到这一点.这种行为已经存在一段时间了，至少可以追溯到 VS 2008.更改默认行为可能会对其他客户造成重大变化，所以我们更愿意保持当前的行为.由于 FOO.TXT 与文件系统的 foo.txt 大致相同，希望使用 __FILE__ 进行任何比较都可以涉及对您的应用程序不区分大小写的比较.

Thanks for noting this. This behavior has existed for a while, at least back to VS 2008. Changing the default behavior could potentially be a breaking change for other customers, so we would prefer to keep the current behavior. Since FOO.TXT is mostly the same as foo.txt for the file system, hopefully using __FILE__ with any comparison can just involve a case-insensitive compare for your application.
