WebExceptionボディを使って全体の応答を取得する方法は？

Question

In WebException GetResponseの本文が表示されません。これはC＃のコードです：

try {     
    return GetResponse(url + "." + ext.ToString(), method, headers, bodyParams); 
} catch (WebException ex) { 
    switch (ex.Status) { 
     case WebExceptionStatus.ConnectFailure: 
     throw new ConnectionException();       
    case WebExceptionStatus.Timeout: 
     throw new RequestTimeRanOutException();      
    case WebExceptionStatus.NameResolutionFailure: 
     throw new ConnectionException();       
    case WebExceptionStatus.ProtocolError: 
      if (ex.Message == "The remote server returned an error: (401) unauthorized.") { 
       throw new CredentialsOrPortalException(); 
      } 
      throw new ProtocolErrorExecption();      
    default: 
      throw; 
    } 

私はヘッダーを参照していますが、本文は表示されません。これは、要求のためにWiresharkから出力されます。

何らかの理由でWebExceptionのメッセージテキストを表示できますか？ ありがとうございます。

Answer 1

var resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd(); 

dynamic obj = JsonConvert.DeserializeObject(resp); 
var messageFromServer = obj.error.message; 

Answer 2

 try 
     { 
      WebClient client = new WebClient(); 
      client.Encoding = Encoding.UTF8; 
      string content = client.DownloadString("https://sandiegodata.atlassian.net/wiki/pages/doaddcomment.action?pageId=524365"); 
      Console.WriteLine(content); 
      Console.ReadKey(); 
     } 
     catch (WebException ex) 
     { 
      var resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd(); 
      Console.WriteLine(resp); 
      Console.ReadKey(); 
     }
