asp.net-core – Asp.Net核心Web应用程序：使用IExceptionFilter

Exception filters handle unhandled exceptions that occur in controller creation,model binding,action filters,or action methods. They won’t catch exceptions that occur in Resource filters,Result filters,or MVC Result execution.

甚至有关何时使用中间件以及何时使用“异常过滤器”的建议：

Exception filters are good for trapping exceptions that occur within MVC actions,but they’re not as flexible as error handling middleware. Prefer middleware for the general case,and use filters only where you need to do error handling differently based on which MVC action was chosen. For example,your app might have action methods for both API endpoints and for views/HTML. The API endpoints could return error information as JSON,while the view-based actions could return an error page as HTML.
