推荐答案偷走here.
Stolen from here.
string GetWebPageContent(string url) { string result = string.Empty; HttpWebRequest request; const int bytesToGet = 1000; request = WebRequest.Create(url) as HttpWebRequest; //get first 1000 bytes request.AddRange(0, bytesToGet - 1); // the following code is alternative, you may implement the function after your needs using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { byte[] buffer = new byte[1024]; int read = stream.Read(buffer, 0, 1000); Array.Resize(ref buffer, read); return Encoding.ASCII.GetString(buffer); } } }
