List ACL

Ive been asked to audit a server with regards to permissions to files and folders, so Ive come up with the idea of using C# to loop through the files and folders and write to a file what permissions each file/folder has.

So looking at the ACL documentation I can use the following code:-

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Security.AccessControl;
using System.Text;
using System.Threading.Tasks;

namespace ACL
{
    class Program
    {
        static void Main(string[] args) {
            getACLInformation("C:\\Rob\\account.sbd");

        }

        static void getACLInformation(string strFile) {
            FileInfo fInfo = new FileInfo(strFile);
            FileSecurity fSecurity = fInfo.GetAccessControl();
        }
    }
}

Select allOpen in new window

However when I look at fSecurity I cannot find out how to get a list of the users/groups and then what permissions they have and if its inherited or not.

Does anyone have any links to documentation or sample code of getting ACL information so I can dump it to a text file for import into a database at a later time for reporting?

Thank you
