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;
        }

    }

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;
}

#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;
}

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;
}

不幸的是，c++标准并没有定义这样处理文件和文件夹的标准方法。

由于没有跨平台的方法，最好的跨平台方法是使用boost文件系统模块之类的库。

跨平台提升方法:

The following function, given a directory path and a file name, recursively searches the directory and its sub-directories for the file name, returning a bool, and if successful, the path to the file that was found. bool find_file(const path & dir_path, // in this directory, const std::string & file_name, // search for this name, path & path_found) // placing path here if found { if (!exists(dir_path)) return false; directory_iterator end_itr; // default construction yields past-the-end for (directory_iterator itr(dir_path); itr != end_itr; ++itr) { if (is_directory(itr->status())) { if (find_file(itr->path(), file_name, path_found)) return true; } else if (itr->leaf() == file_name) // see below { path_found = itr->path(); return true; } } return false; }

对于Unix/Linux系统:

您可以使用opendir / readdir / closedir。

在目录中搜索条目“name”的示例代码如下: Len = strlen(name); Dirp = opendir("."); ((dp = readdir(dirp)) != NULL) 如果(dp - > d_namlen = = len & & !比较字符串(dp - > d_name,名字)){ (空白)closedir (dirp); 返回发现; ｝ (空白)closedir (dirp); 返回NOT_FOUND;

对于基于windows的系统:

你可以使用Win32 API的FindFirstFile / FindNextFile / FindClose函数。

The following C++ example shows you a minimal use of FindFirstFile. #include <windows.h> #include <tchar.h> #include <stdio.h> void _tmain(int argc, TCHAR *argv[]) { WIN32_FIND_DATA FindFileData; HANDLE hFind; if( argc != 2 ) { _tprintf(TEXT("Usage: %s [target_file]\n"), argv[0]); return; } _tprintf (TEXT("Target file is %s\n"), argv[1]); hFind = FindFirstFile(argv[1], &FindFileData); if (hFind == INVALID_HANDLE_VALUE) { printf ("FindFirstFile failed (%d)\n", GetLastError()); return; } else { _tprintf (TEXT("The first file found is %s\n"), FindFileData.cFileName); FindClose(hFind); } }

来自上述msdn页面的源代码。

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;
}
