本文實例類似遍歷一個文件夾然后獲得該文件夾下的文件列表，可以隨意切換文件目錄，本來是用在我們小組寫的簡易ftp服務器上的一個給客戶端顯示的一個小插件，總之單拿出來應該沒啥含量，調用了windows的一些API。
實例代碼：
#include<iostream>#include<stdlib.h>#include<windows.h>#include<fstream>#include<stdio.h>#include<vector>#include<string>#pragma comment (lib, "winmm.lib")using namespace std;void MainMenu(){ printf("請選擇操作/n"); printf("1.顯示當前文件夾的所有文件/n"); printf("2.返回上一級/n"); printf("3.進入文件夾/n"); printf("4.進入指定文件夾/n"); printf("5.退出/n");}void ShowFileList(string filename){ WIN32_FIND_DATAA p; vector<string> filelist; HANDLE h = FindFirstFileA(filename.c_str(), &p); filelist.push_back(p.cFileName); while (FindNextFileA(h, &p)) { filelist.push_back(p.cFileName); if (filelist.back() == "." || filelist.back() == "..") { filelist.pop_back(); } } for (int i = 0; i < filelist.size(); i++) { cout << filelist[i] << endl; }}void ShowLastFileList(string & filepath){ string filepath2 = filepath; string tmp = "../"; tmp += filepath2; filepath = tmp; ShowFileList(tmp);}void ShowSelectFileList(string filepath){ string yourchoose; cin >> yourchoose; yourchoose += '/'; string filepath2 = filepath; yourchoose += filepath2; ShowFileList(yourchoose);}void case4(string filepath){ string filename; cin >> filename; filename += '/'; filename += filepath; ShowFileList(filename);}int main(){ string filepath; filepath = "*.*"; string filePath = filepath; while (1) { system("CLS"); MainMenu(); int n; cin >> n; switch (n) { case 1: system("CLS"); ShowFileList(filePath); system("pause"); break; case 2: system("CLS"); ShowLastFileList(filePath); system("pause"); break; case 3: system("CLS"); ShowSelectFileList(filePath); system("pause"); break; case 4: system("CLS"); case4(filepath); system("pause"); break; case 5: exit(0); break; default: break; } } return 0;} 以上就是C++遍歷文件夾的相關操作，希望對大家的學習有所幫助。
