三种方法:C#获取网页内容

//方法一：
  // Create a request for the URL. 
  WebRequest request = WebRequest.Create("http://www.wowgold300.com/");
  // If required by the server, set the credentials.
  request.Credentials = CredentialCache.DefaultCredentials;
  // Get the response.
  HttpWebResponse response = (HttpWebResponse)request.GetResponse();
  // Display the status.
  Response.Write(response.StatusDescription);
  // Get the stream containing content returned by the server.
  Stream dataStream = response.GetResponseStream();
  // Open the stream using a StreamReader for easy access.
  StreamReader reader = new StreamReader(dataStream,Encoding.Default);
  // Read the content.
  string responseFromServer = reader.ReadToEnd();
  // Display the content.
  Response.Write(responseFromServer);
  // Cleanup the streams and the response.
  reader.Close();
  dataStream.Close();
  response.Close();
  

  //方法二：
  WebClient client = new WebClient();

  // Add a user agent header in case the
  // requested URI contains a query.

  client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

  Stream data = client.OpenRead("http://www.wowgold300.com/");
  StreamReader reader = new StreamReader(data,Encoding.Default);
  string s = reader.ReadToEnd();
  Response.Write(s);
  data.Close();
  reader.Close();
  
  //方法三：
  WebClient client = new WebClient();
