في بلدي ASP.NET مفك التطبيق ، لدي وجهة نظر هذا الدعوة Html.Action("MyAction", this.Model) - لدي سيناريو مماثل في وحدة تحكم مختلفة ويعمل بشكل جيد ، ولكن في هذه الحالة ، فإنه يكسر.أنا وضعت نقطة توقف على السطر الأول من MyAction, ، لكنه لا ينكسر ، لذلك يجب أن يحدث الخطأ قبل تلك النقطة في الكود.

كيف يمكنني الحصول من هذا التتبع المكدس لمعرفة التعليمات البرمجية في طلبي الذي يسبب الاستثناء?
المحلول
هذه المشكلة بالذات هي:
النظام.الويب.هتبكسيبتيون:لا يمكن للخادم تعيين الحالة بعد إرسال رؤوس هتب.
في النظام.الويب.<url>.تعيين _ رمز الحالة (إلى 32 قيمة)
في النظام.الويب.<url>.تعيين _ رمز الحالة (إلى 32 قيمة)
في الكوبالت.موقع الكتروني.منصة.الويب.تحكم.تحكم.أونيكسيبتيون (إكسيبتيونكونتيكست فيلتركونتيكست) في D:\data\Website\App\Website\Controllers\Controller.جيم: الخط 920
يحاول معالج الاستثناء تعيين رمز حالة الاستجابة بعد أن يبدأ الخادم في إخراج محتوى الصفحة.يجب أن تحاول / قبض على مجموعة ستاتوسكود أعتقد ، ووضع نقطة توقف في رمز أونكسيبتيون لمعرفة ما هو الاستثناء الحقيقي، على الرغم من أنه يبدو أن من
d:\data\Website\App\Website\Search\Views\SearchResults.اسبكس: خط 39
صدفة Html.Action يولد عنوان ورل الذي يؤدي إلى إجراء معين ، ولا يستدعي الإجراء نفسه.هل تقصد أتش تي أم أل.العرض?لست متأكدا من أن تمرير النموذج صحيح, على الرغم من أنه من غير المحتمل أن تكون قيم المسار كما هي?

وكنت قادرا على التخلص من هذا عن طريق العودة وجهة نظر () في العمل بخلاف إعادة ريديركتاكتيون ("سوماكتيون");
