如何在标准C ++中以递归方式遍历每个文件/目录？

How do you iterate through every file/directory recursively in standard C++?

推荐答案

在标准C ++中，方式这样做，因为标准C ++没有目录的概念。如果您想扩展网络一点，您可能需要查看 Boost.FileSystem 。这已经被接受包含在TR2中，所以这给你最好的机会，让你的实现尽可能接近标准。

In standard C++, technically there is no way to do this since standard C++ has no conception of directories. If you want to expand your net a little bit, you might like to look at using Boost.FileSystem. This has been accepted for inclusion in TR2, so this gives you the best chance of keeping your implementation as close as possible to the standard.

一个例子，直接从网站：

An example, taken straight from the website:

bool find_file( const path & dir_path,         // in this directory,
                const std::string & file_name, // search for this name,
                path & path_found )            // placing path here if found
{
  if ( !exists( dir_path ) ) return false;
  directory_iterator end_itr; // default construction yields past-the-end
  for ( directory_iterator itr( dir_path );
        itr != end_itr;
        ++itr )
  {
    if ( is_directory(itr->status()) )
    {
      if ( find_file( itr->path(), file_name, path_found ) ) return true;
    }
    else if ( itr->leaf() == file_name ) // see below
    {
      path_found = itr->path();
      return true;
    }
  }
  return false;
}
