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;
        }

    }

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;
    }

};

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; }

来源来自上面提到的boost页面。

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;

来自上述手册页的源代码。

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); } }

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); }

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;
}

或者只是使用特定于操作系统的文件。
