为什么不使用glob()?

#include <glob.h>

glob_t glob_result;
glob("/your_directory/*",GLOB_TILDE,NULL,&glob_result);
for(unsigned int i=0; i<glob_result.gl_pathc; ++i){
  cout << glob_result.gl_pathv[i] << endl;
}

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); }

为什么不使用glob()?

#include <glob.h>

glob_t glob_result;
glob("/your_directory/*",GLOB_TILDE,NULL,&glob_result);
for(unsigned int i=0; i<glob_result.gl_pathc; ++i){
  cout << glob_result.gl_pathv[i] << endl;
}

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;
}

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)。

我希望这段代码对您有所帮助。

#include <windows.h>
#include <iostream>
#include <string>
#include <vector>
using namespace std;

string wchar_t2string(const wchar_t *wchar)
{
    string str = "";
    int index = 0;
    while(wchar[index] != 0)
    {
        str += (char)wchar[index];
        ++index;
    }
    return str;
}

wchar_t *string2wchar_t(const string &str)
{
    wchar_t wchar[260];
    int index = 0;
    while(index < str.size())
    {
        wchar[index] = (wchar_t)str[index];
        ++index;
    }
    wchar[index] = 0;
    return wchar;
}

vector<string> listFilesInDirectory(string directoryName)
{
    WIN32_FIND_DATA FindFileData;
    wchar_t * FileName = string2wchar_t(directoryName);
    HANDLE hFind = FindFirstFile(FileName, &FindFileData);

    vector<string> listFileNames;
    listFileNames.push_back(wchar_t2string(FindFileData.cFileName));

    while (FindNextFile(hFind, &FindFileData))
        listFileNames.push_back(wchar_t2string(FindFileData.cFileName));

    return listFileNames;
}

void main()
{
    vector<string> listFiles;
    listFiles = listFilesInDirectory("C:\\*.txt");
    for each (string str in listFiles)
        cout << str << endl;
}
