如何從網(wǎng)站獲取HTML代碼，保存它并通過(guò)LINQ表達(dá)式查找一些文本？我正在使用以下代碼來(lái)獲取網(wǎng)頁(yè)的來(lái)源：public static String code(string Url){    HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(Url);    myRequest.Method = "GET";    WebResponse myResponse = myRequest.GetResponse();    StreamReader sr = new StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.UTF8);    string result = sr.ReadToEnd();    sr.Close();    myResponse.Close();    return result; }如何在網(wǎng)頁(yè)源代碼的div中查找文本？
