我使用.Net Framework 4.0和C#開發ASP.NET MVC 4 web Api。我無法從HttpError讀取responseStream
我在嘗試從HttpError
獲得響應流時遇到了問題。
在這裏,我產生HttpError
:
m_ExceptionLoggerHelper.LogException("ProductionOrderManagementController", "DoBatchPreparation", Singleton.AutomationServiceVM.COGErrors);
HttpError myCustomError = new HttpError(Singleton.AutomationServiceVM.COGErrors) { { "CustomErrorCode", 4 } };
response = Request.CreateErrorResponse(HttpStatusCode.Conflict, myCustomError);
隨着小提琴手,我得到這個:
HTTP/1.1 409 Conflict
Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1
Server: Microsoft-IIS/8.0
X-AspNet-Version: 4.0.30319
X-SourceFiles: =?UTF-8?B?RDpcRnVlbnRlc1xBdXRvbWF0aW9uTWlkZGxld2FyZVxzcmNcQXV0b21hdGlvbk1pZGRsZXdhcmUuV2ViLkFwaVxhcGlccHJvZHVjdGlvbk9yZGVyc01hbmFnZW1lbnRcTUNHXzIwMTQwODI4MDgyOTQ4XGRvQmF0Y2hQcmVwYXJhdGlvbg==?=
Persistent-Auth: true
X-Powered-By: ASP.NET
Date: Thu, 28 Aug 2014 06:32:36 GMT
Content-Length: 70
{"Message":"Preparation Failed SessionLocked\r\n","CustomErrorCode":4}
在這裏,我捕捉到了異常:
catch (WebException exception)
{
Stream responseStream = exception.Response.GetResponseStream();
using (var reader = new StreamReader(responseStream))
{
string result = reader.ReadToEnd();
Console.WriteLine("Exception: " + result);
}
}
我有問題這裏,new StreamReader(responseStream)
,因爲我得到一個ArgumentException
。在調試時,我檢查了responseStream
,我發現CanRead
屬性是錯誤的。
和'responseStream.Length' throw an excepción type 'System.ObjectDisposedException'
。
我在做什麼錯?
您看到此行爲,因爲該流已被其他地方讀取。 – 2014-08-28 06:52:19
@RobbyCornelissen是的,你是對的。謝謝。 – VansFannel 2014-08-28 06:55:38
