c# - List all files and directories in a directory + subdirectories

Question

I want to list every file and directory contained in a directory and subdirectories of that directory. If I chose C: as the directory, the program would get every name of every file and folder on the hard drive that it had access to.

A list might look like

fd1.txt
fd2.txt
fda
fd
fda1.txt
fda2.txt
fdaa
fda
fd1.txt
fd2.txt
fda
fd
fdaa1.txt
fdaaa
fda1.txt
fdaa
fda1.txt
fdaa
fd1.txt
fda

Answer 1

string[] allfiles = Directory.GetFiles("path/to/dir", "*.*", SearchOption.AllDirectories);

where *.* is pattern to match files

If the Directory is also needed you can go like this:

 foreach (var file in allfiles){
     FileInfo info = new FileInfo(file);
 // Do something with the Folder or just add them to a list via nameoflist.add();
 }
