windows编程列出文件夹内所包含的文件-MSDN例子

Listing the Files in a DirectoryThe following example calls FindFirstFile, FindNextFile, and FindClose to list the files in a specified directory.Note that the only limitation on the number of files a directory can contain is the storage capacity of the disk.#define _WIN32_WINNT 0x0501#include <windows.h>#include <string.h>#include <stdio.h>int main(int argc, char *argv[]){   WIN32_FIND_DATA FindFileData;   HANDLE hFind = INVALID_HANDLE_VALUE;   char DirSpec[MAX_PATH];  // directory specification   DWORD dwError;   printf ("Target directory is %s.\n", argv[1]);   strncpy (DirSpec, argv[1], strlen(argv[1])+1);   strncat (DirSpec, "\\*", 3);   hFind = FindFirstFile(DirSpec, &FindFileData);   if (hFind == INVALID_HANDLE_VALUE)    {      printf ("Invalid file handle. Error is %u\n", GetLastError());      return (-1);   }    else    {      printf ("First file name is %s\n", FindFileData.cFileName);      while (FindNextFile(hFind, &FindFileData) != 0)       {         printf ("Next file name is %s\n", FindFileData.cFileName);      }          dwError = GetLastError();      FindClose(hFind);      if (dwError != ERROR_NO_MORE_FILES)       {         printf ("FindNextFile error. Error is %u\n", dwError);         return (-1);      }   }   return (0);}
