How programmatically set file attribute to not be read-only?

[rcook349]

From within my project, I am opening an file elsewhere on the network and
changing contents within.

When I go to close/save, however, I can't because it's read-only (as it's
checked in).

Can I just flip read-only off, make my changes and save it, and then flip
read only back on (programmatically)? How can I do this, please?

Thanks.

using System.IO;

if (File.Exists(fileName))
{
FileAttributes attrs = File.GetAttributes(fileName);
File.SetAttributes(fileName, attrs & ~FileAttributes.ReadOnly);
MakeTheChanges(fileName);
attrs = File.GetAttributes(fileName);
File.SetAttributes(fileName, attrs | FileAttributes.ReadOnly);
}

There is two calls to GetAttributes, since most likely your
MakeTheChanges sets at least the archive bit.
