在c＃中的webclient沒有得到正確的結果html

Question

我用c＃中的webclient來獲取html結果，但它是不正確的。

這是我的代碼片段。

WebClient client = new WebClient(); 
string htmlCode = client.DownloadString("https://kat.cr/"); 
MessageBox.Show(htmlCode); 

而結果不是在HTML頁面上看到的。

我應該怎麼做，這樣我可以檢索實際的頁面？

html代碼被壓縮..設置AutomaticDecompression爲GZip。 剛剛嘗試這個代碼，它會工作（與YOUE網頁進行了測試）

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress); 
     request.AutomaticDecompression = DecompressionMethods.GZip; 
     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(); 
     } 

既然你問了一個「Web客戶端」解決方案（見註釋）：
因爲WebClient的實現是不減壓，你將不得不製作你自己的DecompressedWebClient。從WebClient類繼承很容易：

public class AutomaticDecompressionWebClient : WebClient 
{ 
    protected override WebRequest GetWebRequest(Uri address) 
    { 
     var request = base.GetWebRequest(address) as HttpWebRequest; 
     if (request == null) throw new InvalidOperationException("You can not use this WebClient implementation with an address that is not an http uri."); 
     request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
     return request; 
    } 
}
