Reading Signature lines using OpenXMlSDK

Question

I just started office development and have been trying to read a word 2013 document that holds signature fields in it using open xml sdk can some one help me how to do that.

 using (var document = WordprocessingDocument.Open(@"D:\Temp_Folder\tempfile.docx", false))
            {                  
                var docPart = document.MainDocumentPart;                      
            }

I have tried reading word file using ELdos (SBOffice) I can get signature lines but not able to get full details related to Signature Lines like Suggested Signer and Suggested Signer email.

Can some one suggest me which I have to prefer OpenXMLSDK or Eldos(SBOffice) bcz i need to find signature fields and then sign them by custom certificate using Third party Signing Service.

The best way would be to use the OpenXMLSDKTool to open the document and it will show you the code necessary to replicate it. I believe it would be within a shape something like

using (var document = WordprocessingDocument.Open("YourDoc.docx", false)
{
    var signature = document.MainDocumentPart.Document.Descendant<DocumentFormat.OpenXML.VML.Office.SignatureLine>().FirstOrDefault();
    var suggestedSigner = signature.SuggestedSigner;
    var suggestedSignerTitle = signature.SuggestedSigner2;
    var suggestedSignerEmail = signature.SuggestedSIgnerEmail;
}

You could get the actual signature image in this same area.
