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

我正在寻找一种方法,或用于将std :: string转换为LPCWSTR的代码片段

感谢MSDN文章的链接.这正是我所寻找的.

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();

std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();

#include 
#include 

. . .

string myStr("My string");
CA2W unicodeStr(myStr);
