Hi,
Thanks for your reply.
INPUT: DOCX file with word TOC. For each TOC items there is a content in the document.
So each content has is own bookmark.

OUTPUT: Same file with content control(Rich text) for each and every bookmark and unique content control name.

I attached expected input and output docx file for you reference.

In simple I want to create content control with bookmark content.

Hi Sathiyamurthy,

Thanks for your patience. In your case, we suggest you following solution.

  1. Extract the TOC contents and save them into separate document
  2. Remove all contents after TOC field from document
  3. Insert content control at the end of document and insert extracted contents

Please read following articles for your kind reference.
How to Extract Selected Content Between Nodes in a Document
Working with Content Control (SDT)

Please get the code of ExtractContent and GenerateDocument methods from above documentation link and use following code example. You may modify the code example according to your requirements. Hope this helps you.

Document doc = new Document(MyDir + "Input.docx");
doc.UpdateFields();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
builder.StartBookmark("_TocEnd");
builder.EndBookmark("_TocEnd");
NodeCollection nodes = doc.GetChildNodes(NodeType.FieldStart, true);
ArrayList tocitems = new ArrayList();
foreach (FieldStart fstart in nodes)
{
    if (fstart.FieldType == Aspose.Words.Fields.FieldType.FieldPageRef)
    {
        String fieldText = fstart.GetField().GetFieldCode();
        if (fieldText.Contains("_Toc"))
        {
            fieldText = fieldText.Substring(fieldText.IndexOf("_Toc"), fieldText.Length - fieldText.IndexOf("_Toc")).Replace("\\h", "").Trim();
            tocitems.Add(fieldText);
        }
    }
    else if (fstart.FieldType == FieldType.FieldTOC)
    {
        if (fstart.GetAncestor(NodeType.StructuredDocumentTag) != null)
        {
            builder.MoveTo(fstart.GetAncestor(NodeType.StructuredDocumentTag).NextSibling);
            builder.StartBookmark("TOCField");
            builder.EndBookmark("TOCField");
        }
        else
        {
            builder.MoveTo(fstart.ParentParagraph.NextSibling);
            builder.StartBookmark("TOCField");
            builder.EndBookmark("TOCField");
        }
    }
}
tocitems.Add("_TocEnd");
ArrayList contents = new ArrayList();
for (int i = 0; i < tocitems.Count - 1; i++)
{
    BookmarkStart bookmarkStart = doc.Range.Bookmarks[tocitems[i].ToString()].BookmarkStart;
    BookmarkStart bookmarkEnd = doc.Range.Bookmarks[tocitems[i + 1].ToString()].BookmarkStart;
    // firstly extract the content between these nodes including the bookmark.
    ArrayList extractedNodes = ExtractContent(bookmarkStart, bookmarkEnd, false);
    Document doc2 = GenerateDocument(doc, extractedNodes);
    doc2.UpdatePageLayout();
    // Remove the empty paragraphs if necessary.
    while (!doc2.LastSection.Body.LastParagraph.HasChildNodes)
    {
        if (doc2.LastSection.Body.LastParagraph.PreviousSibling != null &&
        doc2.LastSection.Body.LastParagraph.PreviousSibling.NodeType != NodeType.Paragraph)
            break;
        doc2.LastSection.Body.LastParagraph.Remove();
        // If the current section becomes empty, we should remove it.
        if (!doc2.LastSection.Body.HasChildNodes)
            doc2.LastSection.Remove();
        if (doc2.LastSection.Body.LastParagraph.Runs.Count == 1 && doc2.LastSection.Body.LastParagraph.Runs[0].Text == ControlChar.PageBreak)
            doc2.LastSection.Body.LastParagraph.Remove();
        // We should exit the loop if the document becomes empty.
        if (!doc2.HasChildNodes)
            break;
    }
    MemoryStream stream = new MemoryStream();
    doc2.Save(stream, SaveFormat.Docx);
    stream.Position = 0;
    contents.Add(stream);
}
// Remove document's contents after TOC field.
builder.MoveToBookmark("TOCField");
builder.InsertBreak(BreakType.SectionBreakNewPage);
builder.StartBookmark("removecontents");
builder.MoveToDocumentEnd();
builder.EndBookmark("removecontents");
doc.Range.Bookmarks["removecontents"].Text = "";
builder.MoveToDocumentEnd();
builder.Writeln();
foreach (MemoryStream item in contents)
{
    StructuredDocumentTag tag = new StructuredDocumentTag(doc, SdtType.RichText, MarkupLevel.Block);
    tag.RemoveAllChildren();
    tag.AppendChild(new Paragraph(doc));
    builder.MoveToDocumentEnd();
    doc.LastSection.Body.AppendChild(tag);
    builder.MoveTo(tag.FirstChild);
    builder.InsertDocument(new Document(item), ImportFormatMode.KeepSourceFormatting);
    doc.LastSection.Body.AppendChild(new Paragraph(doc));
    builder.MoveToDocumentEnd();
    builder.InsertBreak(BreakType.PageBreak);
}
doc.Range.Bookmarks["removecontents"].BookmarkStart.ParentNode.Remove();
doc.UpdateFields();
doc.Save(MyDir + "Out.docx");
