ASP.NET MVC OnException-是否尝试捕获? [英] ASP.NET MVC OnException - Try catch required?

问题描述

我是MVC ASP.NET的新手.我阅读了有关OnException重写方法的信息.我在想，是否应该在Controller或Model上放置try catch {throw}以便调用OnException.或者，我尝试不要求catch，如果发生任何异常，会自动调用OnException吗?

I'm pretty new to MVC ASP.NET. I read about OnException override method. I'm thinking, whether I should put try catch {throw} on Controller or Model in order for OnException to be invoked. OR, I try catch not required, OnException will be invoked autmatically if any exception occurs?

感谢堆.

推荐答案

在操作中发生未处理的异常时调用."

"Called when an unhandled exception occurs in the action."

如果您不处理(即捕获")异常，则应调用OnException方法.

If you don't handle (i.e. "catch") an exception, the OnException method should be called.
