c# acl
fpdragon picture fpdragon · Feb 16, 2011 · Viewed 10.2k times · Source

I already wrote a code which can create a share and change permissions for the current user. The goal was to always allow all for everybody on share level and deny rights on ntfs acl level.

I use a german windows and I noticed that I only can access the everybody user by using "jeder". In english it would be the user "everybody" or "all" I think?! Anyway I'm searching for a way to get the name of the everybody user language independent.

Hope this is possible.

The name that the English version of Windows uses is "Everyone".

You can get the user regardless of language by using the WellKnownSidType.WorldSid value:

var sid = new SecurityIdentifier(WellKnownSidType.WorldSid, null);
var account = (NTAccount) sid.Translate(typeof(NTAccount));
