c# - WebException cómo obtener una respuesta completa con un cuerpo?

Question

En WebException no puedo ver el cuerpo de GetResponse. Este es mi código en C #:

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;
}

Veo el encabezado pero no veo el cuerpo. Esto se envía desde Wireshark para la solicitud:

POST /api/1.0/authentication.json HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Accept: application/json

Connection: close
{"count":0,"startIndex":0,"status":1,"statusCode":500,"error":{"message":"Invalid username or password."}}

¿Es posible de alguna manera ver el texto del mensaje en WebException? Gracias.

Answer 1

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();
}

Answer 2

var resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
dynamic obj = JsonConvert.DeserializeObject(resp);
var messageFromServer = obj.error.message;
