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

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

我认为，下面的代码片段可以用来列出所有的文件。

#include <stdio.h>
#include <dirent.h>
#include <sys/types.h>

int main(int argc, char** argv) { 
    list_dir("myFolderName");
    return EXIT_SUCCESS;
}  

static void list_dir(const char *path) {
    struct dirent *entry;
    DIR *dir = opendir(path);
    if (dir == NULL) {
        return;
    }

    while ((entry = readdir(dir)) != NULL) {
        printf("%s\n",entry->d_name);
    }

    closedir(dir);
}

这是使用的结构(出现在direct .h中):

struct dirent {
    ino_t d_ino; /* inode number */
    off_t d_off; /* offset to the next dirent */
    unsigned short d_reclen; /* length of this record */
    unsigned char d_type; /* type of file */
    char d_name[256]; /* filename */
};

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;
    }

};

基于上面的答案

#include <vector>
#include <string>
#include <algorithm>

#ifdef _WIN32
#include <windows.h>
std::vector<std::string> files_in_directory(std::string path)
{
    std::vector<std::string> files;

    // check directory exists
    char fullpath[MAX_PATH];
    GetFullPathName(path.c_str(), MAX_PATH, fullpath, 0);
    std::string fp(fullpath);
    if (GetFileAttributes(fp.c_str()) != FILE_ATTRIBUTE_DIRECTORY)
        return files;

    // get file names
    WIN32_FIND_DATA findfiledata;
    HANDLE hFind = FindFirstFile((LPCSTR)(fp + "\\*").c_str(), &findfiledata);
    if (hFind != INVALID_HANDLE_VALUE)
    {
        do 
        {
            files.push_back(findfiledata.cFileName);
        } 
        while (FindNextFile(hFind, &findfiledata));
        FindClose(hFind);
    }

    // delete current and parent directories
    files.erase(std::find(files.begin(), files.end(), "."));
    files.erase(std::find(files.begin(), files.end(), ".."));

    // sort in alphabetical order
    std::sort(files.begin(), files.end());

    return files;
}
#else
#include <dirent.h>
std::vector<std::string> files_in_directory(std::string directory)
{
    std::vector<std::string> files;

    // open directory
    DIR *dir;
    dir = opendir(directory.c_str());
    if (dir == NULL)
        return files;

    // get file names
    struct dirent *ent;
    while ((ent = readdir(dir)) != NULL)
        files.push_back(ent->d_name);
    closedir(dir);

    // delete current and parent directories
    files.erase(std::find(files.begin(), files.end(), "."));
    files.erase(std::find(files.begin(), files.end(), ".."));

    // sort in alphabetical order
    std::sort(files.begin(), files.end());

    return files;
}
#endif  // _WIN32

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。

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("./*");
