Answer 1

 case "DocumentFormat.OpenXml.Wordprocessing.SdtBlock":
                        SdtBlock p1 = (SdtBlock)DocElement;
                        content1 = p1.InnerText;

                        IEnumerable<Paragraph> pp = p1.Descendants<Paragraph>();
                        foreach (Paragraph para in pp)
                        {
                         style=   GetParagraphStyleId(para);
                        }

where GetParagraphStyleId(para) has

 public string GetParagraphStyleId(Paragraph p)
    {
        string ParaStyleIdValue = string.Empty;
        if (p.ParagraphProperties != null)
        {
            if (p.ParagraphProperties.ParagraphStyleId != null)
            {
                if (p.ParagraphProperties.ParagraphStyleId.Val != null)
                {
                    ParaStyleIdValue = p.ParagraphProperties.ParagraphStyleId.Val.Value;
                }
            }
        }
        return ParaStyleIdValue;
    }

  Using this i get the Style of the paragraph from sdtContent.
