I am using the TextWriter to try to write to a hidden file, and it is throwing an exception. I can't seem to figure out how to write to a hidden file.
using (TextWriter tw = new StreamWriter(filename))
Unhandled Exception: System.UnauthorizedAccessException:
Access to the path 'E:\*\media\Photos\2006-08\.picasa.ini' is denied.
EDIT 2: This answer solve the problem, but is not the correct way to deal with the problem. You should look for Lucero's answer.
Took this answer from: http://www.dotnetspark.com/Forum/314-accessing-hidden-files-and-write-it.aspx
1- Set File as Visible so it can be overwritten
// Get file info FileInfo myFile= new FileInfo(Environment.CurrentDirectory + @"\hiddenFile.txt"); // Remove the hidden attribute of the file myFile.Attributes &= ~FileAttributes.Hidden;
2- Make changes to the file
// Do foo...
3- Set back file as hidden
// Put it back as hidden myFile.Attributes |= FileAttributes.Hidden;
EDIT: I fixed some problem on my answer as mentionned by briler
