1.添加引用.net 引用Microsoft.mshtml

WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
string str = wc.DownloadString(@"https://www.jb51.net/web/73969.html");

HTMLDocumentClass doc = new HTMLDocumentClass();//獲取html對(duì)象
doc.designMode = "on"; //不讓解析引擎去嘗試運(yùn)行javascript
doc.IHTMLDocument2_write(str);把html 文檔寫入html對(duì)象中
doc.close();關(guān)閉寫流
Console.WriteLine(doc.title);輸出標(biāo)題
Console.WriteLine(doc.body.innerText); 輸出body
Console.ReadKey();
