First you need to download offline samples pack from this link to use the following code example. Then extract the archive and from the DocumentLayoutHelper example, include the RenderedDocument and LayoutEntities source files in to his application.

Here is the sample code:

Document doc = new Document(dataDir + "Test.docx");

// This sample introduces the RenderedDocument class and other related classes which provide an API wrapper for
// the LayoutEnumerator. This allows you to access the layout entities of a document using a DOM style API.

// Create a new RenderedDocument class from a Document object.
RenderedDocument layoutDoc = new RenderedDocument(doc);

// Loop through the layout info of each page
foreach (RenderedPage page in layoutDoc.Pages)
{
    if (page.Columns.Count > 1)
    {
        // Find the last line in the first column on the page.
        RenderedLine lastLine = page.Columns.First.Lines.Last;

        // This is the pargraph which belongs to the last line on the page, implement required logic and checks here.
        Paragraph para = lastLine.Paragraph;
        if (para.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1)
        {
            // Insert a blank paragraph before the last paragraph in the column.
            para.ParentNode.InsertBefore(new Paragraph(doc), para);
        }


        // This is how to get the first line in the second column and the related paragraph.
        // Use this if it is required.
        RenderedLine secondColumnLine = page.Columns[1].Lines.First;
        Paragraph secondColumnPara = lastLine.Paragraph;
    }
}
