根据MSVC ++中的unicode设置自动在std :: string和std :: wstring之间切换?

问题描述

我正在编写一个DLL，希望能够在MSVC ++ 2010中的unicode和多字节设置之间切换.例如，我使用 _T("string")和 LPCTSTR 和 WIN32_FIND_DATA 而不是-W和-A版本等等.

I'm writing a DLL and want to be able to switch between the unicode and multibyte setting in MSVC++2010. For example, I use _T("string") and LPCTSTR and WIN32_FIND_DATA instead of the -W and -A versions and so on.

现在，我想拥有std :: strings，它根据unicode设置在 std :: string 和 std :: wstring 之间变化.那可能吗?否则，这可能最终变得极其复杂.

Now I want to have std::strings which change between std::string and std::wstring according to the unicode setting. Is that possible? Otherwise, this will probably end up getting extremely complicated.

推荐答案

为什么不像Win32 API那样:在内部使用宽字符，并提供 DoSomethingA 函数的字符转换外观将他们的输入转换为Unicode.

Why not do like the Win32 API does: Use wide characters internally, and provide a character-converting facade of DoSomethingA functions which simply convert their input to Unicode.

也就是说，您可以像这样定义 tstring 类型:

That said, you could define a tstring type like so:

#ifdef _UNICODE
typedef std::wstring tstring;
#else
typedef std::string tstring;
#endif

或可能:

typedef std::basic_string<TCHAR> tstring;
