輸出網站X HTML到控制檯在C＃

Question

我在教自己的代碼，所以請原諒無知。

所以我的問題是，爲了能夠輸出特定網站（例如google.com）的HTML到控制檯，我需要閱讀/學習什麼？

謝謝。

Answer 1

我建議你從這裏開始：http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest%28v=VS.90%29.aspx

從本質上講，創建HttpWebRequest，然後調用GetResponse()方法。然後您可以讀取響應流並將其輸出到您的控制檯。

Answer 2

大多數瀏覽器允許您右鍵單擊並選擇「查看源代碼」，這是查看HTML的最簡單方法。

Answer 3

查看WebClient類，特別是MSDN頁面底部的示例。

Answer 4

使用HttpWebRequest創建請求並將響應輸出到控制檯。

using System; 
using System.IO; 
using System.Net; 
using System.Text; 

namespace Examples.System.Net 
{ 
    public class WebRequestGetExample 
    { 
     public static void Main() 
     { 
      // Create a request for the URL.   
      WebRequest request = WebRequest.Create ("http://www.contoso.com/default.html"); 
      // If required by the server, set the credentials. 
      request.Credentials = CredentialCache.DefaultCredentials; 
      // Get the response. 
      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
      // Display the status. 
      Console.WriteLine (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); 
      // Read the content. 
      string responseFromServer = reader.ReadToEnd(); 
      // Display the content. 
      Console.WriteLine (responseFromServer); 
      // Cleanup the streams and the response. 
      reader.Close(); 
      dataStream.Close(); 
      response.Close(); 
     } 
    } 
}

這將這樣的伎倆：

WebClient client = new WebClient(); 
Stream data = client.OpenRead("www.google.com"); 
StreamReader reader = new StreamReader(data); 
string str = reader.ReadLine(); 
Console.WriteLine(str);
