从网站获取HTML代码。您可以使用这样的代码。
string urlAddress = "http://google.com";HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);HttpWebResponse response = (HttpWebResponse)request.GetResponse();if (response.StatusCode == HttpStatusCode.OK){ Stream receiveStream = response.GetResponseStream(); StreamReader readStream = null; if (String.IsNullOrWhiteSpace(response.CharacterSet)) readStream = new StreamReader(receiveStream); else readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet)); string data = readStream.ReadToEnd(); response.Close(); readStream.Close();}这将为您提供从网站返回的 HTML 代码。但是通过 LINQ 查找文本并不是那么容易。也许使用正则表达式会更好，但不能与 HTML
代码一起很好地使用
