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();} );
}

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); }

简单地在Linux中使用ASCI C风格的代码

#include <bits/stdc++.h>
#include <dirent.h>
using namespace std;

int main(){
    DIR *dpdf;
    struct dirent *epdf;
    dpdf = opendir("./");
    
    if (dpdf != NULL){
    while (epdf = readdir(dpdf)){
        cout << epdf->d_name << std::endl;
    }
    }
    closedir(dpdf);
    return 0;
}

希望这能有所帮助!

这对我很有用。如果我不记得出处，我很抱歉。它可能来自一个手册页。

#include <ftw.h>

int AnalizeDirectoryElement (const char *fpath, 
                            const struct stat *sb,
                            int tflag, 
                            struct FTW *ftwbuf) {

  if (tflag == FTW_F) {
    std::string strFileName(fpath);

    DoSomethingWith(strFileName);
  }
  return 0; 
}

void WalkDirectoryTree (const char * pchFileName) {

  int nFlags = 0;

  if (nftw(pchFileName, AnalizeDirectoryElement, 20, nFlags) == -1) {
    perror("nftw");
  }
}

int main() {
  WalkDirectoryTree("some_dir/");
}

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

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;
}
