C++中,宽窄字符互换(wchar_t char wstring string互换)
宽字符转窄字符(wstring转string): std::string WstringToString(const std::wstring& sInput) { if (sInput.length() == 0) return ""; int iBufLen = WideCharToMultiByte(CODE_PAGE, 0, sInput.c_str(), -1, NULL, 0, NULL, NULL); char* buf = new char[iBufLen + 1]; int iLen = WideCharToMultiByte(CODE_PAGE, 0, sInput.c_str(), -1, buf, iBufLen + 1, NULL, NULL); std::string sOutput(buf, iLen); delete[] buf; return sOutput; } 窄字符转宽字符(string转wstring): std::wstring utils::StringToWstring(const std::string& sInput) { if (sInput.length() == 0) return L""; int iBufLen = MultiByteToWideChar(CODE_PAGE, 0, sInput.c_str(), -1, NULL, 0); wchar_t* buf = new wchar_t[iBufLen + 1]; int iLen = MultiByteToWideChar(CODE_PAGE, 0, sInput.c_str(), -1, buf, iBufLen + 1); std::wstring sOutput(buf, iLen); delete[] buf; return sOutput; } 其中,涉及到wchar_t,char_t的转换,可由上面的函数修改一二可得。
