Using DocX to insert text into an existing document.

Maybe I'm just slow, but I found this hard to do. Here is a simple bit of code that finally did it. It seemed to me that I should have been able to use some simpler, more obvious methods to achieve this, but they just didn't work for me.

private void button1_Click(object sender, RoutedEventArgs e)
{
    using (DocX doc = DocX.Load(@"..\..\Templates\source.docx"))
    {

        int index = FindParagraphIndexContaining("@Marker@", doc);

        Paragraph p = doc.Paragraphs[index];

        Paragraph p2 = p.InsertParagraphAfterSelf("");
        p2.Append("Here is a new paragraph.").Font(new System.Drawing.FontFamily("Verdana")).FontSize(11);
        p2.IndentationBefore = 1.0f;

        p.Remove(false);

        doc.SaveAs(@"..\..\Templates\saved.docx");

        MessageBox.Show("Done!");
    }
}

private int FindParagraphIndexContaining(string text, DocX doc)
{
    int i;

    for (i = 0; i < doc.Paragraphs.Count; i++)
    {
        if (doc.Paragraphs[i].FindAll(text).Count > 0)
        {
            return i;
        }
    }
    return -1;
}
