WebResponse是一个抽象类，意味着它首先是一个保留字。第二 - 为了使用WebResponse，一个类必须从WebResponse继承即ie。
public class WR : WebResponse
{
//Code
}
也。您当前的代码与Html Agility Pack无关。如果要将网页的html加载到HtmlDocument中，请执行以下操作：
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();
try{
var temp = new Uri(url);
var request = (HttpWebRequest)WebRequest.Create(temp);
request.Method = "GET";
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var stream = response.GetResponseStream())
{
htmlDoc.Load(stream, Encoding.GetEncoding("iso-8859-9"));
}
}
}catch(WebException ex){
Console.WriteLine(ex.Message);
}
然后，为了获取Html文档中的节点，您必须使用xPath，如下所示：
HtmlNode node = htmlDoc.DocumentNode.SelectSingleNode("//body");
Console.WriteLine(node.InnerText);
