在WebException中,我看不到GetResponse的主体。这是我在C#中的代码:WebException如何获得整体响应与身体?
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;
}
我看到标题,但没有看到正文。这是从Wireshark输出的请求:

是否有可能以某种方式在WebException中查看消息文本? 谢谢。
你试过(HttpWebResponse)we.Response;我们在哪里发现了WebException? – 2012-08-06 13:06:01
为了在重新抛出的异常中保存堆栈跟踪,不要使用'throw ex;'而只是'throw;'(在默认情况下)。另外(如果需要的话),我会把原来的WebException放入你的自定义异常的InnerException(通过适当的构造函数)。 – user1713059 2014-04-04 17:38:27
