using signtool.exe to scan files in windows-based application

I am assigned to implement a windows-based C# program to pickup a folder and use signtool.exe to scan/sign all documents.

I am able to get the list of the files in that folder. Now how do I use the signtool.exe to sign them? The client machines don't have the signtool.exe installed anywhere.

Edited: Instead of using external tool to do signature check, I could use the x509Certificates to check directly. My solution is below for whoever needs in the future.

Sorry, it has been a while. I found a simple solution for this. Just hope in the future, people would look for it:

        public static string CheckSignature(string FileName)
    {
        //X509Certificate2 cert;
        try
        {
            var signer = X509Certificate.CreateFromSignedFile(FileName);
            var cert = new X509Certificate2(signer);
            return "Digitally signed by: " + cert.SubjectName.Name;
        }
        catch (Exception)
        {
            return "NOT digitally signed.";
        }
    }

Don't forget including: using System.Security.Cryptography.X509Certificates;

You would launch signtool.exe with code similar to:

var info = new ProcessStartInfo("<path.to>\signtool.exe", "<command line arguments>");
var p = Process.Start(info);
p.WaitForExit();
