string 与wstring 的转换

std::wstring StringToWString(const std::string &str)
{
std::wstring wstr(str.length(),L' ');
std::copy(str.begin(), str.end(), wstr.begin());
return wstr;
}

//只拷贝低字节至string中
std::string WStringToString(const std::wstring &wstr)
{
std::string str(wstr.length(), ' ');
std::copy(wstr.begin(), wstr.end(), str.begin());
return str;
}

上面的对于英文字符串是正确的，对于中文是错误的，下面的代码则适用于中英文！

std::string AVentilationGraph::wstring2string(const std::wstring &wstr)

{

    std::string curLocale = setlocale(LC_ALL, NULL);        // curLocale = "C";

    setlocale(LC_ALL, "chs");

    const wchar_t* _Source = wstr.c_str();

    size_t _Dsize =  * wstr.size() + ;

    char *_Dest = new char[_Dsize];

    memset(_Dest, , _Dsize);

    wcstombs(_Dest, _Source, _Dsize);

    std::string result = _Dest;

    delete[]_Dest;

    setlocale(LC_ALL, curLocale.c_str());

    return result;

}

//wstring 转 string

std::wstring AVentilationGraph::string2wstring(const std::string &str)

{

    setlocale(LC_ALL, "chs");

    const char* _Source = str.c_str();

    size_t _Dsize = str.size() + ;

    wchar_t *_Dest = new wchar_t[_Dsize];

    wmemset(_Dest, , _Dsize);

    mbstowcs(_Dest, _Source, _Dsize);

    std::wstring result = _Dest;

    delete[]_Dest;

    setlocale(LC_ALL, "C");

    return result;

}
