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;
    }

};

char **getKeys(char *data_dir, char* tablename, int *num_keys)
{
    char** arr = malloc(MAX_RECORDS_PER_TABLE*sizeof(char*));
int i = 0;
for (;i < MAX_RECORDS_PER_TABLE; i++)
    arr[i] = malloc( (MAX_KEY_LEN+1) * sizeof(char) );  


char *buf = (char *)malloc( (MAX_KEY_LEN+1)*sizeof(char) );
snprintf(buf, MAX_KEY_LEN+1, "%s/%s", data_dir, tablename);

DIR* tableDir = opendir(buf);
struct dirent* getInfo;

readdir(tableDir); // ignore '.'
readdir(tableDir); // ignore '..'

i = 0;
while(1)
{


    getInfo = readdir(tableDir);
    if (getInfo == 0)
        break;
    strcpy(arr[i++], getInfo->d_name);
}
*(num_keys) = i;
return arr;
}

};

一个函数就足够了，你不需要使用任何第三方库(对于Windows)。

#include <Windows.h>

vector<string> get_all_files_names_within_folder(string folder)
{
    vector<string> names;
    string search_path = folder + "/*.*";
    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) ) {
                names.push_back(fd.cFileName);
            }
        }while(::FindNextFile(hFind, &fd)); 
        ::FindClose(hFind); 
    } 
    return names;
}

PS:正如@Sebastian提到的，你可以改变*。*到*。ext，以便只获得该目录中的ext文件(即特定类型的文件)。

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;
}

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;
        }

    }
