I am iterating through all the files in a folder and just want their names in a string. I want to get a string from a std::filesystem::path. How do I do that?

My code:

#include <string>
#include <iostream>
#include <filesystem>
namespace fs = std::experimental::filesystem;

int main()
{
    std::string path = "C:/Users/user1/Desktop";
    for (auto & p : fs::directory_iterator(path))
        std::string fileName = p.path;
}

However I get the following error:

non-standard syntax; use '&' to create a pointer to a member.

The examples given in the accepted answer, using the UTF-8 operations, are fine and a good guideline. There is just one error in the introductory explanation given in the answer, which Windows/MSVC developers should be aware of:

The string() method does not return the natively-encoded string (which would be std::wstring() on Windows), but rather it always returns a std::string. It also tries to convert the path to the local encoding, which is not always possible, if the path contains a unicode character not representable in the current code page and then the method throws an exception!

If you actually want the behavior that is described in the answer (method returns native string, i.e., std::string on Linux and std::wstring on Windows), you would have to use the native() method or the implicit conversion based on std::filesystem::path::operator string_type(), but as @tambre correctly pointed out in the examples, you should consider using the UTF-8 versions throughout.
