在IIS中的NullReferenceException但不在VS 2015

-2

我一直在使用Extjs 6處理MVC，當我在Visual Studio 2015上運行時完美工作，但是當我將它部署到Windows 2012 R2中的IIS 8.5時，我得到空引用異常。該錯誤立即發生，儘快在登錄後以及頁面嘗試加載時發生。信息： Versiónde Microsoft .NET Framework：4.0.30319;版本ASP.NET:4.6.1055.0 裝配=「System.Web.Mvc，版本= 5.2.3.0 在Windows 2012 R2 IIS：8.5在IIS中的NullReferenceException但不在VS 2015

謝謝

根據我的觀點是，在DataContext不實例化的問題：HiplotTMdbConexion的DataContext =新HiplotTMdbConexion當項目部署在IIS中時。一些想法？謝謝。 – IcebergDelphi

出於某種原因：

檢查你的代碼。

檢查Web.config文件是否爲空引用異常。

堆棧溢出不是一個傳統的論壇。留下您對該答案的評論，並且在您未發佈答案時不要創建答案。在做這樣的事情之前研究別人如何使用網站。所有關於問題的細節都必須放入問題本身，您可以隨時輕鬆編輯。 –
