FindFirstFile的预期输入类型是什么?

如何将wstring转换为字符串?

这是一个Windows解决方案。

因为我想要传入std::string并返回一个字符串向量，所以我必须进行一些转换。

#include <string>
#include <Windows.h>
#include <vector>
#include <locale>
#include <codecvt>

std::vector<std::string> listFilesInDir(std::string path)
{
    std::vector<std::string> names;
    //Convert string to wstring
    std::wstring search_path = std::wstring_convert<std::codecvt_utf8<wchar_t>>().from_bytes(path);
    WIN32_FIND_DATA fd;
    HANDLE hFind = FindFirstFile(search_path.c_str(), &fd);
    if (hFind != INVALID_HANDLE_VALUE) 
    {
        do 
        {
            // read all (real) files in current folder
            // , delete '!' read other 2 default folder . and ..
            if (!(fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) 
            {
                //convert from wide char to narrow char array
                char ch[260];
                char DefChar = ' ';
                WideCharToMultiByte(CP_ACP, 0, fd.cFileName, -1, ch, 260, &DefChar, NULL);
                names.push_back(ch);
            }
        } 
        while (::FindNextFile(hFind, &fd));
        ::FindClose(hFind);
    }
    return names;
}

#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;
}

简单中有美，通过添加/s键，我们还可以遍历子目录。

system("dir /n /b /s * > file_names.txt");

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;
    }

};

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;
}
