Working with directories and Files

Question

How to enumerate hidden files /directories in C# 4.0

Basically I use

var directories = new DirectoryInfo(@"DirectoryName")
                .EnumerateDirectories()
                .Where(**What is the condition that should go here?**)

Answer 1

Use FileAttributes.Hidden

var Directories = new DirectoryInfo(@"DirectoryName")
                .EnumerateDirectories()
                .Where(x => x.Attributes.HasFlag(FileAttributes.Hidden))
                .Select(x => x.Name);
