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)。

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;
    }

};

Shreevardhan的设计也适用于遍历子目录:

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

using namespace std;
namespace fs = filesystem;
int main()
{
    string path = "\\path\\to\\directory";
    // string path = "/path/to/directory";
    for (auto & p : fs::recursive_directory_iterator(path))
        cout << p.path() << endl;
}

编译:cl /EHsc /W4 /WX /std:c++17 ListFiles.cpp

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); }

我试图遵循两个回答中给出的示例，可能值得注意的是，似乎std::filesystem::directory_entry已被更改为不重载<<操作符。而不是std::cout << p << std::endl;我必须使用以下能够编译并让它工作:

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

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

试图将p单独传递给std::cout <<会导致丢失重载错误。

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!
