Html Agility Pack c# Paragraph parsing problem

I am having a couple of issues with my code, I am trying to pull every paragraph from a page, but at the moment it is only selecting the last paragraph.

here is my code.

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//div[@id='body']/p"))
{
  string text = node.InnerText;
  lblTest2.Text = text;
}

IMO, XPath is no fun. I'd recommend using LINQ syntax instead:

foreach (var node in doc.DocumentNode
    .DescendantNodes()
    .Single(x => x.Id == "body")
    .DescendantNodes()
    .Where(x => x.Name == "p")) 
{
    string text = node.InnerText;
    lblTest2.Text = text;
}

In your loop you are taking the current node innerText and assigning it to the label. You do this to each node, so of course you only see the last one - you are not preserving the previous ones.

Try this:

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//div[@id='body']/p"))
{
  string text = node.InnerText;
  lblTest2.Text += text + Environment.NewLine;
}
