Hi scarrier92,

Thanks for your inquiry.
Please first get the IssuerName, and then extract the value according to the information. Here is sample code for your reference.

Code: Select all

            PdfSignature signatureOne = signatures[0];
            string s  =  signatureOne.Certificate.IssuerName.Name;
            Regex regex = new Regex("CN.*");
            string value = regex.Match(s).Value.Replace("CN=","");

If there is any qeustion, welcome to get it back to us.

I guess the solution is working in most case. In my use case it's actually related to :

http://www.e-iceblue.com/forum/pdf-2-level-of-certificate-t6432.html

And so I'm still waiting a solution for that one.

Thank you

Dear scarrier92,

Thanks for your waiting.
That thread has updated, now please try to get the subject of the second certificate, and the information after CN is what you want.

Code: Select all

            X509Certificate2Collection collection = signatureOne.Certificates;
            string s = collection[0].Subject.ToString();

If there is any quesiton, welcome to get it back to us.
