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();} );
}

我建议在这个可重用的包装器中使用glob。它生成一个vector<string>，对应于符合glob模式的文件路径:

#include <glob.h>
#include <vector>
using std::vector;

vector<string> globVector(const string& pattern){
    glob_t glob_result;
    glob(pattern.c_str(),GLOB_TILDE,NULL,&glob_result);
    vector<string> files;
    for(unsigned int i=0;i<glob_result.gl_pathc;++i){
        files.push_back(string(glob_result.gl_pathv[i]));
    }
    globfree(&glob_result);
    return files;
}

然后可以使用普通的系统通配符模式调用，例如:

vector<string> files = globVector("./*");

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;
}

尝试x平台方法

或者只是使用特定于操作系统的文件。

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/");
}
