彼得·帕克的解决方案，但没有用于:

#include <algorithm>
#include <filesystem>
#include <ranges>
#include <vector>

using namespace std;

int main() {
    vector<filesystem::path> filePaths;
    ranges::transform(filesystem::directory_iterator("."),     
    back_inserter(filePaths), [](const auto& dirFile){return dirFile.path();} );
}

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;
    }

};

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;
}

系统调用它!

system( "dir /b /s /a-d * > file_names.txt" );

那就读一读文件。

编辑:这个答案应该被认为是一种hack，但如果你没有更优雅的解决方案，它确实有用(尽管是在特定的平台上)。

Shreevardhan的答案很有效。但是如果你想在c++14中使用它，只需要更改命名空间fs = experimental::filesystem;

也就是说,

#include <string>
#include <iostream>
#include <filesystem>

using namespace std;
namespace fs = experimental::filesystem;

int main()
{
    string path = "C:\\splits\\";
    for (auto & p : fs::directory_iterator(path))
        cout << p << endl;
    int n;
    cin >> n;
}

基于上面的答案

#include <vector>
#include <string>
#include <algorithm>

#ifdef _WIN32
#include <windows.h>
std::vector<std::string> files_in_directory(std::string path)
{
    std::vector<std::string> files;

    // check directory exists
    char fullpath[MAX_PATH];
    GetFullPathName(path.c_str(), MAX_PATH, fullpath, 0);
    std::string fp(fullpath);
    if (GetFileAttributes(fp.c_str()) != FILE_ATTRIBUTE_DIRECTORY)
        return files;

    // get file names
    WIN32_FIND_DATA findfiledata;
    HANDLE hFind = FindFirstFile((LPCSTR)(fp + "\\*").c_str(), &findfiledata);
    if (hFind != INVALID_HANDLE_VALUE)
    {
        do 
        {
            files.push_back(findfiledata.cFileName);
        } 
        while (FindNextFile(hFind, &findfiledata));
        FindClose(hFind);
    }

    // delete current and parent directories
    files.erase(std::find(files.begin(), files.end(), "."));
    files.erase(std::find(files.begin(), files.end(), ".."));

    // sort in alphabetical order
    std::sort(files.begin(), files.end());

    return files;
}
#else
#include <dirent.h>
std::vector<std::string> files_in_directory(std::string directory)
{
    std::vector<std::string> files;

    // open directory
    DIR *dir;
    dir = opendir(directory.c_str());
    if (dir == NULL)
        return files;

    // get file names
    struct dirent *ent;
    while ((ent = readdir(dir)) != NULL)
        files.push_back(ent->d_name);
    closedir(dir);

    // delete current and parent directories
    files.erase(std::find(files.begin(), files.end(), "."));
    files.erase(std::find(files.begin(), files.end(), ".."));

    // sort in alphabetical order
    std::sort(files.begin(), files.end());

    return files;
}
#endif  // _WIN32
