c# - htmlagilitypack - remove script and style?

Question

Im using the following method to extract text form html:

    public string getAllText(string _html)
    {
        string _allText = "";
        try
        {
            HtmlAgilityPack.HtmlDocument document = new HtmlAgilityPack.HtmlDocument();
            document.LoadHtml(_html);


            var root = document.DocumentNode;
            var sb = new StringBuilder();
            foreach (var node in root.DescendantNodesAndSelf())
            {
                if (!node.HasChildNodes)
                {
                    string text = node.InnerText;
                    if (!string.IsNullOrEmpty(text))
                        sb.AppendLine(text.Trim());
                }
            }

            _allText = sb.ToString();

        }
        catch (Exception)
        {
        }

        _allText = System.Web.HttpUtility.HtmlDecode(_allText);

        return _allText;
    }

Problem is that i also get script and style tags.

How could i exclude them?

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);

doc.DocumentNode.Descendants()
                .Where(n => n.Name == "script" || n.Name == "style")
                .ToList()
                .ForEach(n => n.Remove());
