Folder access rights and permisions

Question

 

Hello,

 

I'm trying to make a program in c# in which I need to know (just get the information, no need to change it) the security and sharing access rights (read, write, full permissions...) on a specific folder for each group and user. I have already managed to know the security rights for my personnal account (System.Security.Principal.WindowsIdentity getWindowsIdentity) but I need to get this for everybody.

 

How can I get the list of groups and users with customed permissions in my program (the same list as in the folder properties window in explorer). As soon as I get this list, I think that I'll be able to know the folder rights for each user account like I did for mine.

 

I'll take care of the sharing permissions later but if you have good resources about this topic, it could be helpful.

 

Thank you.

Hi

 

Thanks! I finally found the solution to get information i needed. Here is how i've done, it might help:

 

 

As I said, I aimed get the list of groups and users with customed permissions in my program (the same list as in the "user and groupe names" from the security tab in a folder properties). For exemple here, I wanted to get admin, créateur, marc...

 

Code Snippet

   DirectorySecurity ds = new DirectorySecurity(@"C:\", AccessControlSections.All);
 
            AuthorizationRuleCollection arc = ds.GetAccessRules(true, true, typeof(NTAccount));
            foreach (FileSystemAccessRule fsar in arc)
            {
                Console.WriteLine(fsar.IdentityReference + " : " + fsar.AccessControlType + "->" + fsar.FileSystemRights);
            }

 

This code gives you:

 

Everyone : Allow -> ReadAndExecute, Synchronize
CREATOR OWNER : Allow -> FullControl
NT AUTHORITY\SYSTEM : Allow -> FullControl
BUILTIN\Administrators : Allow -> FullControl
BUILTIN\Users : Allow -> ReadAndExecute, Synchronize
BUILTIN\Users : Allow -> CreateFiles, Synchronize
BUILTIN\Users : Allow -> AppendData, Synchronize
ANCALAGON\Mary : Allow -> ReadAndExecute, Synchronize

 

Bye
