我想将 std::string 转换为 const wchar_t *

If you have a std::wstring object, you can call c_str() on it to get a wchar_t*:

std::wstring name( L"Steve Nash" );
const wchar_t* szName = name.c_str();

然而，由于您在一个狭窄的字符串上操作，您首先需要将其加宽.这里有多种选择；一种是使用Windows内置的MultiByteToWideChar 例程.这会给你一个 LPWSTR，它等价于 wchar_t*.

Since you are operating on a narrow string, however, you would first need to widen it. There are various options here; one is to use Windows' built-in MultiByteToWideChar routine. That will give you an LPWSTR, which is equivalent to wchar_t*.
