C# Code to Edit Table Of Content & Insert Paragraph between TOC Entries in Word Document

Document doc = new Document("D:\\Temp\\sample-input.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

BookmarkStart bmStart = null;

foreach (FieldStart field in doc.GetChildNodes(NodeType.FieldStart, true))
{
    if (field.FieldType.Equals(FieldType.FieldHyperlink))
    {
        FieldHyperlink hyperlink = (FieldHyperlink)field.GetField();
        if (hyperlink.SubAddress != null && hyperlink.SubAddress.StartsWith("_Toc"))
        {
            Paragraph tocItem = (Paragraph)field.GetAncestor(NodeType.Paragraph);
            if (tocItem != null && tocItem.ToString(SaveFormat.Text).Trim().StartsWith("Heading 3.1.2"))
            {
                builder.MoveTo(tocItem.FirstChild);
                bmStart = builder.StartBookmark("bm");
