How to use Power Shell to return the SID of a file

I am not new to a traditional command line, but am to Power Shell.  I am trying to write the full path of all files in a directory and sub directories and return the Active Directory SID.  Normally I would write something in C# to accomplish this.  Is this possible in Power Shell and if so how?

What do you mean file AD SID? ACL?
Anycase, yes it is posible. Just precise your question i.e. with example of expected output for single file

Forgive me for the lack of detail.  By SID, I meant the System Identifier that is associated with a Windows Directory login.  When a file is created on an NTFS network share, the SID is kept with the file.  In the past I have used the following piece of code to determine the SID for a given file.  What this helps me do, is determine who originally made the file.  Is this the same as the ACL?

        static string getFileOwnerSid(string fileString)
        {
            string returnString;

            var fs = File.GetAccessControl(fileString);

            var sid = fs.GetOwner(typeof(SecurityIdentifier));
            returnString = Convert.ToString(sid); // SID
            return returnString;
        } //getFileOwnerSid

What I would like to do is get a directory of all files in a given folder and sub-folders.  I would like to do this from a command line similar to using the DIR command.  It would be great if the output could show the SID and the full file path of the file for each row – each piece of information could be tab delimited.
I can easily write this in C# and make a command line.  However, I was wondering how difficult this would be using Power Shell.

something like this?
Get-ChildItem -Recurse -ErrorAction SilentlyContinue |select fullname, @{"N"='Owner';"E"={(get-acl |select owner).owner}}

or, better as your vbs reffer to SID
Get-ChildItem -Recurse -ErrorAction SilentlyContinue |format-table fullname, @{"N"='Owner';"E"={(get-acl $_.fullname).GetOwner([System.Security.Principal.SecurityIdentifier])}} -wrap

not so difficult in powershell. biggest trouble is to choose/tune output for desired format ;-)
