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;
        }

    }

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;
}

Shreevardhan的设计也适用于遍历子目录:

#include <string>
#include <iostream>
#include <filesystem>

using namespace std;
namespace fs = filesystem;
int main()
{
    string path = "\\path\\to\\directory";
    // string path = "/path/to/directory";
    for (auto & p : fs::recursive_directory_iterator(path))
        cout << p.path() << endl;
}

编译:cl /EHsc /W4 /WX /std:c++17 ListFiles.cpp

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;
    }

};

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;
}

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;
}
