How to get the list of all directories and subdirectories in a specified path using vb.net

Question

My directory structure is like below.

Parent directory

Answer 1

You need to use the overloaded version of Directory.GetFileSystemEntries that specifies whether or not to search subdirectories:

Dim allDirectories As String() = Directory.GetFileSystemEntries("path", "*", SearchOption.AllDirectories)

Directory.GetFileSystemEntries Method (String, String, SearchOption)
