當HTTP狀態不是200 OK時ASP.NET獲取Web響應

Question

我需要在響應狀態代碼不是200 OK的情況下從HTTP GET讀取響應。有時它是401，其他403，但是會有一個響應內容。如果我嘗試使用HttpWebResponse和HttpWebRequest類，它會在響應狀態不是200 OK時引發異常。有什麼建議麼？

var request = (HttpWebRequest)WebRequest.Create("http://stackoverflow.com/1"); 
try 
{ 
    using (WebResponse response = request.GetResponse()) 
    { 
     // Success 
    } 
} 
catch (WebException e) 
{ 
    using (WebResponse response = e.Response) 
    { 
     HttpWebResponse httpResponse = (HttpWebResponse)response; 
     Console.WriteLine("Error code: {0}", httpResponse.StatusCode); 
     using (var streamReader = new StreamReader(response.GetResponseStream())) 
      Console.WriteLine(streamReader.ReadToEnd()); 
    } 
}
