我有一些路径，我想从它只是子目录路径得到（我的意思只是说在他们那里没有发现其它目录中的文件路径）。

I have some path , and i want to get from it only the subdirectories paths (i mean only paths that under them where not found another directories only files).

任何聪明的方式来做到这一点？

Any smart way to do so ?

多谢了。

推荐答案

这是我的理解是要列出一个给定的路径下只包含文件的子目录。

It is my understanding that you want to list the subdirectories below a given path that contain only files.

static IEnumerable<string> GetSubdirectoriesContainingOnlyFiles(string path)
{
  return from subdirectory in Directory.GetDirectories(path, "*", SearchOption.AllDirectories)
         where Directory.GetDirectories(subdirectory).Length == 0
        select subdirectory;
}
