creating hidden files using .NET

Question

How can I create or mark a file as hidden using .NET?

Answer 1

Use File.SetAttributes. "Hidden" is just one of many available attributes.

Answer 2

You set the hidden attribute of the file.

There are several ways of doing so - with File.SetAttributes or FileInfo.Attributes, you simply set the FileAttributes enumeration flag to hidden:

string path = @"c:\myfile.txt";
File.SetAttributes(path, FileAttributes.Hidden);

Answer 3

I assume you are referring to setting the file attribute to hidden in the file system. Please take a look at this link

Answer 4

If it's an existing file, i.e. not one you've just created, don't just:

File.SetAttributes(path, FileAttributes.Hidden);

or certain other attributes it may have will be lost, so rather you should:

File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);
