Add comment to heading below the content

[Princeshivananjappa]

Hi Team,
I want to find the particular heading in the document then I need to check the heading below the particular content. both the heading and content matched and do not need to add a comment.
if the heading below the content is not matched we need to add the comment.

Please find the below input and expected output.

string description = "This is the Heading 3";
string heading = "Heading 3";
var listHeadings = doc.GetChildNodes(NodeType.Paragraph, true).Cast<Paragraph>().Where(p => p.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1);
foreach (Paragraph paragraph in listHeadings)
{
    if (paragraph.ToString(SaveFormat.Text).Trim().Equals(heading, StringComparison.InvariantCultureIgnoreCase))
    {
        var commenttextTopMarginText = "This description is worng";
        Comment comment = new Comment(doc, "mmh", "007", DateTime.Today);
        comment.Paragraphs.Add(new Paragraph(doc));
        comment.FirstParagraph.AppendChild(new Run(doc, commenttextTopMarginText));
        CommentRangeStart start = new CommentRangeStart(doc, comment.Id);
        CommentRangeEnd end = new CommentRangeEnd(doc, comment.Id);

        paragraph.PrependChild(start);
        paragraph.AppendChild(comment);
        paragraph.AppendChild(end);
    }
}

@Princeshivananjappa,

Here is the code you are looking for:

 private void Logic(Document doc)
 {
     string description = "This is the Heading 3";
     string heading = "Heading 3";
     var listParagraphs = doc.GetChildNodes(NodeType.Paragraph, true).Cast<Paragraph>();

     Paragraph headingReference = null;
     foreach (Paragraph paragraph in listParagraphs)
     {
         // Last iteration we found the heading
         if (headingReference != null)
         {
             // This paragraph must not be heading 1 or it means there is no content
             if (paragraph.ParagraphFormat.StyleIdentifier != StyleIdentifier.Heading1 &&
                 !paragraph.ToString(SaveFormat.Text).Trim().Equals(description, StringComparison.InvariantCultureIgnoreCase)) // ! or Negated or not equals
             {
                 var commenttextTopMarginText = "This description is wrong";
                 Comment comment = new Comment(doc, "mmh", "007", DateTime.Today);
                 comment.Paragraphs.Add(new Paragraph(doc));
                 comment.FirstParagraph.AppendChild(new Run(doc, commenttextTopMarginText));
                 CommentRangeStart start = new CommentRangeStart(doc, comment.Id);
                 CommentRangeEnd end = new CommentRangeEnd(doc, comment.Id);

                 paragraph.PrependChild(start);
                 paragraph.AppendChild(comment);
                 paragraph.AppendChild(end);             
             }
			 
             //we break always after the heading was found
             break;
         }

         if(paragraph.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1 &&
            paragraph.ToString(SaveFormat.Text).Trim().Equals(heading, StringComparison.InvariantCultureIgnoreCase))
         {
             headingReference = paragraph;
             continue;
         }
     }
