将 CString 转换为 const char*
如何在我的 Unicode MFC 应用程序中将 CString 转换为 const char*?
How do I convert from CString to const char* in my Unicode MFC application?
推荐答案
要将 TCHAR CString 转换为 ASCII，请使用 CT2A 宏 - 这也将允许您将字符串转换为 UTF8(或任何其他 Windows 代码页):
To convert a TCHAR CString to ASCII, use the CT2A macro - this will also allow you to convert the string to UTF8 (or any other Windows code page):
// Convert using the local code page
CString str(_T("Hello, world!"));
CT2A ascii(str);
TRACE(_T("ASCII: %S
"), ascii.m_psz);
// Convert to UTF8
CString str(_T("Some Unicode goodness"));
CT2A ascii(str, CP_UTF8);
TRACE(_T("UTF8: %S
"), ascii.m_psz);
// Convert to Thai code page
CString str(_T("Some Thai text"));
CT2A ascii(str, 874);
TRACE(_T("Thai: %S
"), ascii.m_psz);
还有一个宏可以从 ASCII -> Unicode (CA2T) 转换，只要你有 VS2003 或更高版本，你就可以在 ATL/WTL 应用程序中使用这些.
There is also a macro to convert from ASCII -> Unicode (CA2T) and you can use these in ATL/WTL apps as long as you have VS2003 or greater.
