Я пытаюсь создать построитель форм в MVC, а в моем файле FormController.cs я получаю предупреждающее сообщение «Недоступный код обнаружен». Я использую Visual Studio 2013 для создания метода, а также для метода редактирования. Вот оба метода: ** Знаки были проблемой!Недопустимый код, обнаруженный в файле MVC FormController.cs

Вы прокомментировали строки 'if (ModelState.IsValid), так что у вас есть один оператор returnRirectirectToAction (..)' (а не в 'if' block') - все, что после этого никогда не будет выполнено - его уже вышли из-за перенаправления. –
Что вы думаете? Какую часть предупреждения вы не понимаете? Есть ли что-то, что вы ожидаете от этого кода, что это не так? – CodeCaster
