下面是c++ 11中使用boost::filesystem库获取目录中的文件名(不包括文件夹名)的一个非常简单的代码:

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main()
{
    path p("D:/AnyFolder");
    for (auto i = directory_iterator(p); i != directory_iterator(); i++)
    {
        if (!is_directory(i->path())) //we eliminate directories
        {
            cout << i->path().filename().string() << endl;
        }
        else
            continue;
    }
}

输出如下:

file1.txt
file2.dat

看看这个使用win32 api的类。只需要构造一个实例，提供您想要清单的文件夹名，然后调用getNextFile方法从目录中获取下一个文件名。我认为它需要windows.h和stdio.h。

class FileGetter{
    WIN32_FIND_DATAA found; 
    HANDLE hfind;
    char folderstar[255];       
    int chk;

public:
    FileGetter(char* folder){       
        sprintf(folderstar,"%s\\*.*",folder);
        hfind = FindFirstFileA(folderstar,&found);
        //skip .
        FindNextFileA(hfind,&found);        
    }

    int getNextFile(char* fname){
        //skips .. when called for the first time
        chk=FindNextFileA(hfind,&found);
        if (chk)
            strcpy(fname, found.cFileName);     
        return chk;
    }

};

        {
            cout << i->path().filename().string() << endl;
        }
        else
            continue;
    }
}

输出如下:

file1.txt
file2.dat

这个实现实现了您的目的，用指定目录的内容动态填充字符串数组。

int exploreDirectory(const char *dirpath, char ***list, int *numItems) {
    struct dirent **direntList;
    int i;
    errno = 0;

    if ((*numItems = scandir(dirpath, &direntList, NULL, alphasort)) == -1)
        return errno;

    if (!((*list) = malloc(sizeof(char *) * (*numItems)))) {
        fprintf(stderr, "Error in list allocation for file list: dirpath=%s.\n", dirpath);
        exit(EXIT_FAILURE);
    }

    for (i = 0; i < *numItems; i++) {
        (*list)[i] = stringDuplication(direntList[i]->d_name);
    }

    for (i = 0; i < *numItems; i++) {
        free(direntList[i]);
    }

    free(direntList);

    return 0;
}

FindFirstFile的预期输入类型是什么?

如何将wstring转换为字符串?

这是一个Windows解决方案。

因为我想要传入std::string并返回一个字符串向量，所以我必须进行一些转换。

#include <string>
#include <Windows.h>
#include <vector>
#include <locale>
#include <codecvt>

std::vector<std::string> listFilesInDir(std::string path)
{
    std::vector<std::string> names;
    //Convert string to wstring
    std::wstring search_path = std::wstring_convert<std::codecvt_utf8<wchar_t>>().from_bytes(path);
    WIN32_FIND_DATA fd;
    HANDLE hFind = FindFirstFile(search_path.c_str(), &fd);
    if (hFind != INVALID_HANDLE_VALUE) 
    {
        do 
        {
            // read all (real) files in current folder
            // , delete '!' read other 2 default folder . and ..
            if (!(fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) 
            {
                //convert from wide char to narrow char array
                char ch[260];
                char DefChar = ' ';
                WideCharToMultiByte(CP_ACP, 0, fd.cFileName, -1, ch, 260, &DefChar, NULL);
                names.push_back(ch);
            }
        } 
        while (::FindNextFile(hFind, &fd));
        ::FindClose(hFind);
    }
    return names;
}

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

int main() {
    std::string path = "/path/to/directory";
    for (const auto & entry : fs::directory_iterator(path))
        std::cout << entry.path() << std::endl;
}
