windows编程列出文件夹内所包含的文件-MSDN例子

Listing the Files in a Directory The 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); }
