wstring與string互轉

std::string ws2s(const std::wstring& ws)
{
	std::string curLocale = setlocale(LC_ALL, NULL);        // curLocale = "C";
	setlocale(LC_ALL, "chs");
	const wchar_t* _Source = ws.c_str();
	size_t _Dsize = 2 * ws.size() + 1;
	char *_Dest = new char[_Dsize];
	memset(_Dest,0,_Dsize);
	size_t convertedNum = 0;
	wcstombs_s(&convertedNum,_Dest,_Dsize,_Source,_Dsize);
	std::string result = _Dest;
	delete []_Dest;
	setlocale(LC_ALL, curLocale.c_str());
	return result;
}

std::wstring s2ws(const std::string& s)
{
	setlocale(LC_ALL, "chs"); 
	const char* _Source = s.c_str();
	size_t _Dsize = s.size() + 1;
	wchar_t *_Dest = new wchar_t[_Dsize];
	wmemset(_Dest, 0, _Dsize);
	size_t convertedNum = 0;
	mbstowcs_s(&convertedNum,_Dest,_Dsize,_Source,_Dsize);
	std::wstring result = _Dest;
	delete []_Dest;
	setlocale(LC_ALL, "C");
	return result;
}

這2個函數的出處由於比較久，忘了從哪裏來的了，反正不是我的原創      現在我把這個博客當成了一些操作記錄和代碼儲存工具來用了，所以從資料裏貼出來……
