Get all sub directories that only contain files

Question

I have a path and I want to list the subdirectories under it, where each subdirectory doesn't contain any other directory. (Only those subdirectories which don't contain folders, but only files.)

Any smart way to do so?

Answer 1

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;
}

Answer 2

DirectoryInfo

DirectoryInfo dInfo = new DirectoryInfo(<path to dir>);
DirectoryInfo[] subdirs = dInfo.GetDirectories();
