如何在C ++（Unicode）中将std :: string转换为LPCWSTR

Question

我正在寻找将std :: string转换为LPCWSTR的方法或代码段

Answer 1

std::wstring s2ws(const std::string& s)

{

    int len;

    int slength = (int)s.length() + 1;

    len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0); 

    wchar_t* buf = new wchar_t[len];

    MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);

    std::wstring r(buf);

    delete[] buf;

    return r;

}

std::wstring stemp = s2ws(myString);

LPCWSTR result = stemp.c_str();
