@Princeshivananjappa Please see our documentation to learn how to work with comment. In your case you can use code like this to add comment to the paragraph in your document:

Document doc = new Document(@"C:\Temp\in.docx");

// Get heading paragraph.
Paragraph heading = doc.GetChildNodes(NodeType.Paragraph, true).Cast<Paragraph>()
    .Where(p => (p.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1)).FirstOrDefault();

// Create and add a comment.
Comment comment = new Comment(doc, "James Bond", "007", DateTime.Today);
comment.Paragraphs.Add(new Paragraph(doc));
comment.FirstParagraph.AppendChild(new Run(doc, "This is my cool comment!"));
CommentRangeStart start = new CommentRangeStart(doc, comment.Id);
CommentRangeEnd end = new CommentRangeEnd(doc, comment.Id);

heading.PrependChild(start);
heading.AppendChild(end);
heading.AppendChild(comment);

doc.Save(@"C:\Temp\out.docx");

@alexey.noskov Thank you for the quick response. I used the same code for a run but it’s thouing error like Run doesn’t contain a definition of PrependChild. Kindly help me.

public static void comment(Document doc)
{
    int value = 14;
    foreach (Paragraph para in doc.GetChildNodes(NodeType.Paragraph, true))
    {
        if (para.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1)
        {
            foreach (Run r in para.Runs)
            {

                if (r.Font.Size.ToString() != Convert.ToDouble(value).ToString())
                {
                    var commenttextRightMarginText = "Heading1 Level1 Font [Font Size]: Old value:" + r.Font.Size + ", New value: " + Convert.ToDouble(value);

                    r.Font.Size = Convert.ToDouble(value);

                    // Create and add a comment.
                    Comment comment = new Comment(doc, "James Bond", "007", DateTime.Today);
                    comment.Paragraphs.Add(new Paragraph(doc));
                    comment.FirstParagraph.AppendChild(new Run(doc, commenttextRightMarginText));
                    CommentRangeStart start = new CommentRangeStart(doc, comment.Id);
                    CommentRangeEnd end = new CommentRangeEnd(doc, comment.Id);

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

@Princeshivananjappa Paragraph is a composite node, while Run is inline node and cannot contain children. So if you need to comment some Run, you should insert comment nodes on the same level as Run. For example see the following code:

// Create and add a comment.
Comment comment = new Comment(doc, "James Bond", "007", DateTime.Today);
comment.Paragraphs.Add(new Paragraph(doc));
comment.FirstParagraph.AppendChild(new Run(doc, "This is my cool comment!"));
CommentRangeStart start = new CommentRangeStart(doc, comment.Id);
CommentRangeEnd end = new CommentRangeEnd(doc, comment.Id);

// Use InsertBefore and InsettAfer methods to insert comment nodes.
run.ParentNode.InsertBefore(start, run);
run.ParentNode.InsertAfter(comment, run);
run.ParentNode.InsertAfter(end, run);
