How can I check Accessibility permissions on a folder using C #?

Hi I want to check if a specific folder is user accessible. for normal rights to shares, I can obtain information on

DirectoryInfo di = new DirectoryInfo(path);
    DirectorySecurity acl = di.GetAccessControl(AccessControlSections.All);
    AuthorizationRuleCollection rules = acl.GetAccessRules(true, true, typeof(NTAccount));

    //Go through the rules returned from the DirectorySecurity
    foreach (AuthorizationRule rule in rules)
    {
        //If we find one that matches the identity we are looking for
        if (rule.IdentityReference.Value.Equals(NtAccountName, StringComparison.CurrentCultureIgnoreCase))
        {
            //Cast to a FileSystemAccessRule to check for access rights
            if ((((FileSystemAccessRule)rule).FileSystemRights & FileSystemRights.WriteData) > 0)
            {
                Console.WriteLine(string.Format("{0} has write access to {1}", NtAccountName, path));
            }
            else
            {
                Console.WriteLine(string.Format("{0} does not have write access to {1}", NtAccountName, path));
            }
        }
    }

      

        
        
        
      

    

But the problem with this approach is that if you share a folder with the Accessibility option as shown in the figure, it does not display the log entry.

How to calculate it?
