C + + Traverse folder get file list _c language

The example of this article is similar to traverse a folder and then get a list of files under the folder , you can switch the file directory, is used in our team to write a simple FTP server to the client to display a small plug-in, in short, should not be a single take out what content, A number of Windows APIs were invoked.

Instance code:

#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 ("Select operation \ n");
  printf ("1. Display all files in the current folder \ n");
  printf ("2. Return to previous level \ n");
  printf ("3. Enter folder \ n");
  printf ("4. Enter the specified folder \ n");
printf ("5. exit \ 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;
 }

The above is the C + + Traversal folder related operations, I hope to help you learn.
