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;
}

试试来自direct .h的scandir()

男人scandir ()

简单地在Linux中使用ASCI C风格的代码

#include <bits/stdc++.h>
#include <dirent.h>
using namespace std;

int main(){
    DIR *dpdf;
    struct dirent *epdf;
    dpdf = opendir("./");
    
    if (dpdf != NULL){
    while (epdf = readdir(dpdf)){
        cout << epdf->d_name << std::endl;
    }
    }
    closedir(dpdf);
    return 0;
}

希望这能有所帮助!

下面是c++ 11中使用boost::filesystem库获取目录中的文件名(不包括文件夹名)的一个非常简单的代码:

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main()
{
    path p("D:/AnyFolder");
    for (auto i = directory_iterator(p); i != directory_iterator(); i++)
    {
        if (!is_directory(i->path())) //we eliminate directories
        {
            cout << i->path().filename().string() << endl;
        }
        else
            continue;
    }
}

输出如下:

file1.txt
file2.dat

尝试x平台方法

或者只是使用特定于操作系统的文件。

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;
}
