    HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(Url);
    myRequest.Method = "GET";
    WebResponse myResponse = myRequest.GetResponse();

推荐答案

HTML入门$ C $从c网站。你可以用code这样的。

Getting HTML code from a website. You can use code like this.

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 (response.CharacterSet == null)
  {
     readStream = new StreamReader(receiveStream);
  }
  else
  {
     readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
  }

  string data = readStream.ReadToEnd();

  response.Close();
  readStream.Close();
}

这会给你返回的 HTML $ C $从c网站。但通过查找文本的 LINQ 不是那么容易。
也许这是更好地使用常规的前pression但不发挥好 HTML code

This will give you the returned HTML code from the website. But find text via LINQ is not that easy. Perhaps it is better to use regular expression but that does not play well with HTML code
