如何删除错误类型没有定义构造函数

Question

我正在尝试解析一个网页.但它给出了一个错误.请帮我.谢谢.

这是代码:

   static void myMain()
    {
        using (var client = new WebClient())
        {
            string data = client.DownloadString("http://www.google.com");
            HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(data);

            var nodes = doc.DocumentNode.SelectNodes("//a[@href]");
            foreach (HtmlNode link in nodes)
            {
                HtmlAttribute att = link.Attributes["href"];
                Console.WriteLine(att.Value);
            }
        }
    }

它给出了错误,The type 'System.Windows.Form.HtmlDocument' has no constructors defined.我已经包含了HAP.

谢谢

更改

HtmlDocument doc = new HtmlDocument(); 

至

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

因为你不想工作 System.Windows.Form.HtmlDocument
