这个答案应该适用于Windows用户在使用Visual Studio和任何其他答案时遇到的问题。

Download the dirent.h file from the github page. But is better to just use the Raw dirent.h file and follow my steps below (it is how I got it to work). Github page for dirent.h for Windows: Github page for dirent.h Raw Dirent File: Raw dirent.h File Go to your project and Add a new Item (Ctrl+Shift+A). Add a header file (.h) and name it dirent.h. Paste the Raw dirent.h File code into your header. Include "dirent.h" in your code. Put the below void filefinder() method in your code and call it from your main function or edit the function how you want to use it. #include <stdio.h> #include <string.h> #include "dirent.h" string path = "C:/folder"; //Put a valid path here for folder void filefinder() { DIR *directory = opendir(path.c_str()); struct dirent *direntStruct; if (directory != NULL) { while (direntStruct = readdir(directory)) { printf("File Name: %s\n", direntStruct->d_name); //If you are using <stdio.h> //std::cout << direntStruct->d_name << std::endl; //If you are using <iostream> } } closedir(directory); }

#include<iostream>
#include <dirent.h>
using namespace std;
char ROOT[]={'.'};

void listfiles(char* path){
    DIR * dirp = opendir(path);
    dirent * dp;
    while ( (dp = readdir(dirp)) !=NULL ) {
         cout << dp->d_name << " size " << dp->d_reclen<<std::endl;
    }
    (void)closedir(dirp);
}

int main(int argc, char **argv)
{
    char* path;
    if (argc>1) path=argv[1]; else path=ROOT;

    cout<<"list files in ["<<path<<"]"<<std::endl;
    listfiles(path);

    return 0;
}

这对我很管用。它用所有文件的名称(没有路径)写入一个文件。然后它读取txt文件并为你打印出来。

void DisplayFolderContent()
    {

        system("dir /n /b * > file_names.txt");
        char ch;
        std::fstream myStream("file_names.txt", std::fstream::in);
        while (myStream.get(ch))
        {
            std::cout << ch;
        }

    }

我认为，下面的代码片段可以用来列出所有的文件。

#include <stdio.h>
#include <dirent.h>
#include <sys/types.h>

int main(int argc, char** argv) { 
    list_dir("myFolderName");
    return EXIT_SUCCESS;
}  

static void list_dir(const char *path) {
    struct dirent *entry;
    DIR *dir = opendir(path);
    if (dir == NULL) {
        return;
    }

    while ((entry = readdir(dir)) != NULL) {
        printf("%s\n",entry->d_name);
    }

    closedir(dir);
}

这是使用的结构(出现在direct .h中):

struct dirent {
    ino_t d_ino; /* inode number */
    off_t d_off; /* offset to the next dirent */
    unsigned short d_reclen; /* length of this record */
    unsigned char d_type; /* type of file */
    char d_name[256]; /* filename */
};

您可以使用std::experimental:: filesystem::directory_iterator()来获取根目录下的所有直接文件。然后，读取这些路径文件的名称。

#include <iostream>
#include <filesystem>
#include <string>
#include <direct.h>
using namespace std;
namespace fs = std::experimental::filesystem;
void ShowListFile(string path)
{
for(auto &p: fs::directory_iterator(path))  /*get directory */
     cout<<p.path().filename()<<endl;   // get file name
}

int main() {

ShowListFile("C:/Users/dell/Pictures/Camera Roll/");
getchar();
return 0;
}

或者只是使用特定于操作系统的文件。
