本文介绍了一个使用C++编写的递归函数，该函数能够遍历指定路径下的所有文件和子文件夹，并将文件名收集到一个字符串列表中。通过实例展示了如何调用此函数并打印出所有文件。

typedef CList<CString,CString&> StringList;

void GetAllFiles(CString path,StringList& filenamelist, POSITION headpos)
{
WIN32_FIND_DATA fdata = {0};
_chdir(path.GetBuffer(0));

if(fdata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
  if(fdata.cFileName[0]!='.')

   CString childpath;
   childpath.Format("%s\\%s",path,fdata.cFileName);
   SetCurrentDirectory(childpath.GetBuffer(0));
   GetAllFiles(childpath,filenamelist,headpos);
   SetCurrentDirectory("..");
  }

  FileName.Format("%s\\%s",path,fdata.cFileName);
  filenamelist.InsertAfter(headpos,FileName);
}

while(FindNextFile(hSearch, &fdata))

  if(fdata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)  {
   if(fdata.cFileName[0]!='.')
   {

    CString childpath;
    childpath.Format("%s\\%s",path,fdata.cFileName);
    SetCurrentDirectory(childpath.GetBuffer(0));
    GetAllFiles(childpath,filenamelist,headpos);
    SetCurrentDirectory("..");
   }
  }
  else
  {
   FileName.Format("%s\\%s",path,fdata.cFileName);
   filenamelist.InsertAfter(headpos,FileName);
  }
}

FindClose(hSearch);
}

// 调用

StringList FileNameList;
CString Head = ".";
POSITION pos = FileNameList.AddHead(Head);
GetAllFiles(Path,FileNameList,pos);
int nCount = FileNameList.GetCount();
for (int i=1;i<nCount;i++)
{
  POSITION pos = FileNameList.FindIndex(i);
  CString FileName = FileNameList.GetAt(pos);
  cout << FileName.GetBuffer(0) << endl;
}
